ISMB Translational Medicine SIG 2016: Reproducible Genomic Interpretation Too...Katie Fisch, Ph.D.
TransMed 2016 SIG presentation for ISMB 2016 in Orlando, Florida (https://www.iscb.org/ismb2016program/ismb2016-sigs#transmed) profiling a precision medicine case study and open source notebooks developed for translational medicine (Jupyter-Genomics https://github.com/ucsd-ccbb/jupyter-genomics).
This research aimed to determine the quality of life of patients who had undergone surgery for major bile duct injuries. The study involved 90 patients at Istanbul University Istanbul Medical Faculty. Data was collected using a patient information form and the SF-36 health survey. The data was analyzed using SPSS software and various statistical tests. It was found that factors like education level, marital status, health insurance, income, number of children, work status, and living situation influenced changes in quality of life. It was proposed to increase awareness of postoperative complications, develop new assessment tools specific to bile duct injuries, and conduct further research across treatment to better understand recovery.
Recruitment Metrics from TogetherRA: A Study in Rheumatoid Arthritis Patients...John Reites
- A study utilized a direct-to-patient recruitment model to collect patient-reported outcomes, medical records, and genomic data from rheumatoid arthritis patients. This approach resulted in rapid enrollment, with the first patient in to last patient in period taking only 18 weeks.
- A total of 1,000 patients enrolled and provided various levels of data, with 48% providing all data types. Compliance with individual study components ranged from 59-82%.
- Future analyses will examine the completeness and quality of the medical record and genomic data collected, and explore genomic predictors of biological response. The direct-to-patient approach showed potential for efficiently obtaining multiple data types from patients.
Smoking is linked to worse outcomes in men undergoing radical prostatectomy for prostate cancer. The study found that smokers had higher cancer volumes and greater amounts of high-grade cancer compared to non-smokers. Heavy smokers, defined as those with a 20 pack-year or more history of smoking, faced a higher risk of biochemical recurrence following surgery. Smoking independently predicted larger cancer volumes, more high-grade cancer, and increased risk of PSA levels rising after surgery. The researchers conclude that smoking history should be considered in risk assessment models, as quitting smoking may help prostate cancer survival.
This document outlines a study on soft tissue tumors conducted by Dr. Shameera Begum at the Department of Pathology. The study aims to analyze approximately 150 soft tissue tumor cases over 5 years to understand the clinicopathological profile, incidence of benign vs malignant tumors, age/sex/site distribution, histopathological patterns, and use of immunohistochemistry. Both retrospective and prospective approaches will be used involving case file review, H&E staining, and special stains/immunohistochemistry where needed. Statistical analysis will be performed and ethical protocols followed to anonymize patient identities and obtain consent.
This brief paper will help you to understand survival analysis. This type of analysis is important when the time between exposure and event is of clinical interest. The misconception that mortality and survival are interchangeable comes from the lay use of the terms. Learn more and let me know if you have any questions.

Computational methods for case-cohort studiessahirbhatnagar
This document discusses case-cohort study designs. It begins with an introduction to case-cohort studies and their advantages over traditional cohort studies. Specifically, case-cohort studies select a random subcohort from the full cohort and collect detailed exposure data on both the subcohort and all cases. This reduces costs compared to a full cohort study. However, variance estimation can be computationally challenging. The document then provides an example case-cohort study and discusses challenges in estimating risks using the Cox proportional hazards model with case-cohort data. It aims to explain case-cohort designs and demonstrate accurate effect estimation methods.

This document discusses genomic strategies in clinical oncology and molecular medicine. It outlines a routine genomic workflow in clinical oncology that involves tumor biopsy, DNA/RNA sequencing, clinical and scientific analysis of the data, and delivery of results to genetic counselors. The results can identify actionable mutations, variants of unknown significance, or incidental findings. The genomic data can then guide therapeutic decisions, applied and clinical research through clinical trials, drug discovery, and genomic surveillance. Single-cell RNA sequencing research has shown selective evolution of cancer cell populations found in RNA and heterogeneity in cancer cell populations in response to chemotherapy and drug holidays. The author's research has involved controlling the stress response in precancerous cells, using CRISPR technology to develop
An experimental personalized melanoma vaccine was tested on 3 patients with advanced melanoma. The vaccine targeted mutations unique to each patient's cancer and resulted in an increased immune response against their tumors. However, the researchers emphasize this only shows an immunological response, not clinical efficacy, and a larger clinical trial is needed to evaluate the vaccine's ability to treat cancer or improve patient outcomes. While other immunotherapies exist for melanoma, this customized approach could potentially be used to target other cancers if further research demonstrates its safety and effectiveness.

The document emphasizes the importance of temporal sequence between exposure and outcome and minimizing biases and confounding when using these observational study designs.
Cervical cancer is the leading gynecological malignancy worldwide. This paper presents diverse classification techniques and shows the advantage of feature selection approaches to the best predicting of cervical cancer disease. There are thirty-two attributes with eight hundred and fifty-eight samples. Besides, this data suffers from missing values and imbalance data. Therefore, over-sampling, under-sampling and embedded over and under sampling have been used. Furthermore, dimensionality reduction techniques are required for improving the accuracy of the classifier. Therefore, feature selection methods have been studied as they divided into two distinct categories, filters and wrappers. The results show that age, first sexual intercourse, number of pregnancies, smokes, hormonal contraceptives, and STDs: genital herpes are the main predictive features with high accuracy with 97.5%. Decision Tree classifier is shown to be advantageous in handling classification assignment with excellent performance.
Discuss the role of precision medicine in breast cancerAbdullahi Sanusi
Precision medicine plays an important role in contemporary breast cancer therapy by tailoring treatment to individual patients based on their specific genetic, biomarker, and other characteristics. This allows for more accurate predictions about treatment effectiveness and side effects. Key aspects of precision medicine in breast cancer include molecular subtyping of tumors to determine optimal surgical, radiation, chemotherapy, and targeted therapy approaches. Challenges remain in fully implementing precision approaches due to limitations in diagnostic facilities, accounting for tumor heterogeneity, and developing targeted therapies.
A cohort study involves observing a group of individuals over time to examine exposure-outcome relationships. Key characteristics include prospectively following exposed and unexposed groups to compare disease outcomes. Major biases include loss to follow up and misclassification of exposure status. Cohort studies are well-suited for rare exposures and allow examination of multiple outcomes, but require large sample sizes and are time-consuming.

The 25-year follow-up of the Canadian National Breast Screening Study found:
1) Annual mammography screening in women aged 40-59 did not reduce mortality from breast cancer beyond physical examination alone.
2) A total of 1,190 breast cancers were diagnosed during the initial 5-year screening period and a further 5,193 cancers in the follow-up period.
3) The cumulative mortality from breast cancer was similar between the mammography arm (500 deaths) and control arm (505 deaths).
4) After 15 years of follow-up, 106 additional cancers were observed in the mammography arm, attributed to over-diagnosis or the detection of cancers that would not have otherwise become

Volcanic activity is related to tectonic plate boundaries and hotspots. Eruptions can be basic, acid, fissure or composite depending on the magma composition. Primary hazards include lava flows, pyroclastic flows, ashfall and gases. Secondary hazards arise from landslides, lahars, mudflows and acidic rain. The 1985 eruption of Nevado del Ruiz in Colombia caused lahars that killed over 20,000 people after melting the volcano's glaciers.
The document describes the 1997 eruption of the Soufriere Hills Volcano on the island of Montserrat in the Caribbean. The eruption violently erupted in June 1997, disturbing the island's peaceful existence. It devastated seven villages and resulted in the deaths of nine farmers who were found dead in the exclusion zone. The small volcanic island was evacuated but some farmers remained in the exclusion zone.
This document discusses industrial accidents and hazards. It defines an industrial accident as an occurrence in an industrial establishment that causes bodily injury, making a worker unfit for duties for at least 48 hours. Industrial accidents are classified by severity, from first aid accidents to fatal accidents. Causes of accidents include unsafe conditions, unsafe acts, plant equipment, environment, people, and work systems. The document also covers hazard identification, control techniques like elimination and engineering controls, and the importance of accident prevention through education, enforcement and engineering approaches.
The document summarizes the 2010 eruption of the Eyjafjallajokull volcano in Iceland. The eruption occurred under a glacier, causing massive ash clouds that rose to 30,000 feet and closed airspace across Europe. This caused major economic disruptions costing airlines over $2 billion. While Iceland suffered some damage like flooded roads and ash-damaged homes, its preparedness as an MEDC with monitoring technology and emergency plans meant the eruption caused no loss of life.

This study examined the relationship between arsenic exposure, tobacco use, and lung cancer risk in a cohort of 3,278 miners in China with at least 10 years of arsenic exposure and 27 years of follow up. The results showed that lung cancer risk increased linearly with cumulative arsenic exposure and was greater at higher exposure concentrations over shorter durations compared to lower concentrations over longer durations. Joint analysis found a sub-multiplicative interaction between arsenic exposure and tobacco use, suggesting the factors influence lung cancer through different pathways. Limitations included the study only included miners with substantial arsenic exposure.
This summary provides an overview of key information from the document:
1) The document reviews several epidemiological studies that examine the relationship between smokeless tobacco use and oral cancer risk. Case control and cohort studies from Sweden, India, and Norway generally found increased risks, though the magnitude of risk depended on the type of smokeless tobacco.
2) A review of 21 studies found that chewing tobacco and moist snuff carried low cancer risks under 2, while dry snuff was associated with higher relative risks from 4 to 13. However, studies may have overestimated risks by not adequately controlling for smoking and drinking.
3) Another review of 65 studies also noted small increased risks from case control studies, but cohort studies
This document summarizes a case-control study examining occupational risk factors for bladder cancer. The study included 152 bladder cancer patients and compared them to a control group matched for age, sex, and location. It found significantly higher rates of cigarette smoking and opium use in the cancer patients. When controlling for smoking, opium use on its own was still a risk factor. Working in metal industries like welding or with tin carried the highest risk, with an odds ratio of 10.629 for bladder cancer. Other occupations did not show significant associations. The study suggests cigarette smoking, opium use, and occupations involving metal work are risk factors for developing bladder cancer.
Head and neck squamous cell carcinoma in young adults: a hospital based study...Shashwat Mishra
This study examined 362 patients with head and neck squamous cell carcinoma (HNSCC) treated at a hospital in India between 2015-2015. The results showed that HNSCC was more common in males, with chewing tobacco and betel nut being significant risk factors. The most common tumor sites were the mouth in younger patients (age <39) and hypopharynx in older patients (age >39). Chewing tobacco, betel nut, and smoking were positively associated with tumor site. Lower education levels also correlated with higher rates of tobacco and betel nut use. The study concludes tobacco use, male gender, and low education increase HNSCC risk in this population.
Trial randomizzato di screening del cancro della prostata: 20 anni di follow-upMerqurioEditore_redazione
This 20-year randomized controlled trial assessed whether screening for prostate cancer reduces mortality. It found:
1) 85 cases of prostate cancer were diagnosed through screening vs 292 cases in the control group.
2) The risk ratio for death from prostate cancer was 1.16, not a statistically significant difference.
3) After adjusting for age, the hazard ratio was 1.58, a statistically significant difference, suggesting screening may reduce mortality. However, the absolute reduction in mortality was small.
1) The study examined risk factors and tumor histopathology of 224 uninsured female breast cancer patients in Pakistan.
2) Results showed patients had higher rates of early marriage, abortion, stress, family cancer history, and diseases like diabetes and hypertension.
3) Histopathological analysis found patients aged 40 and under had higher rates of grade III tumors, 1-3 lymph node metastases, and hormone receptor negative status, indicating more advanced disease.
Genotoxic and Reprotoxic Effects of Afabazole Tobacco Smokeijtsrd
The harms of smoking are well known. Smokers are more likely to develop lung cancer and other malignant tumors, cardiovascular pathologies and chronic respiratory diseases. The genotoxic and reprotoxic effects of Afabazole tobacco smoke are discussed in detail in this article. Ergashkulov Mexroj Xurshedovich | Yuldashev S. J. "Genotoxic and Reprotoxic Effects of Afabazole Tobacco Smoke" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-6 | Issue-4 , June 2022, URL: https://www.ijtsrd.com/papers/ijtsrd50040.pdf Paper URL: https://www.ijtsrd.com/medicine/ophthalmology/50040/genotoxic-and-reprotoxic-effects-of-afabazole-tobacco-smoke/ergashkulov-mexroj-xurshedovich
This study compared outcomes for head and neck cancer patients based on age. Younger patients (≤40 years old) had significantly better 5-year survival rates (65%) than middle-aged (41-64 years old, 52%) or older patients (≥65 years old, 38%). Younger patients also developed fewer recurrent tumors or new primary tumors. However, the reasons for the differences in outcomes based on age are unclear. The study aimed to analyze outcomes while controlling for other factors like smoking history, tumor stage, and treatment received to better understand the independent impact of age.
This case control study examined the relationship between occupational risk factors and bladder cancer in northern Israel. The study found that 71% of bladder cancer patients were manual workers compared to 42% of controls, and 59% of cancer patients reported chemical exposures at work versus 14% of controls. Specific exposures like gasoline, fuels, concrete, and paints were reported more by cancer patients. As expected, smoking was strongly associated with bladder cancer risk. While some occupational exposures were linked to higher cancer rates, the study did not find a statistical association between bladder cancer and occupational exposures in multivariate analysis. The findings suggest a need for prevention among occupationally exposed workers.
The document summarizes a study that aimed to predict clinical failure in patients with metastatic prostate cancer by identifying genes related to prostate cancer. Researchers analyzed gene expression levels of androgen receptor, estrogen receptor, and stem cell markers in cancer and stromal cells collected via laser capture microdissection from biopsy samples of 76 patients. Logistic regression analysis showed that expression of Sox2, Her2, and CRP in cancer cells and AR and ER in stromal cells highly predicted prostate-specific antigen recurrence. Ten factors were identified as prognostic for cancer-specific survival, including expression of Oct1, TRIM36, Sox2, c-Myc, AR, Klf4, ER, and clinical parameters. Patients were divided into risk

This survey aimed to assess clinicians' use of stereotactic radiotherapy and targeted therapies for metastatic renal cell carcinoma and determine support for future clinical trials. The primary objective was to evaluate the proportion of clinicians using radiotherapy for metastatic renal cell carcinoma. Secondary objectives included evaluating the proportion using targeted therapies and radiotherapy simultaneously, stopping targeted therapies for radiotherapy, and supporting further research. The online survey was distributed to members of urology and oncology groups in Australia and New Zealand to collect data on current practices. Results and conclusions will be presented at an upcoming conference.
Molecular Detection of Epstein Barr Virus, Human Papilloma Virus Types 16,18 ...CrimsonpublishersCancer
This study investigated the presence of Epstein Barr virus (EBV) and human papillomavirus (HPV) types 16 and 18 in breast cancer patients in Khartoum State, Sudan. DNA was extracted from paraffin-embedded tumor specimens from 70 breast cancer patients and tested for EBV and HPV using PCR. The results showed that 8 patients (11.4%) were positive for EBV and 7 patients (10%) were positive for HPV type 18, but none were positive for HPV type 16. This provides evidence that EBV and HPV type 18 may play a role in breast cancer in this population. The findings help establish baseline data on viral causes of breast cancer in Sudan and highlight the need for improved
Identifying individuals at high risk for lung cancer in AustraliaSax Institute
This document summarizes research evaluating a risk prediction tool called PLCOm2012 for identifying high-risk individuals for lung cancer screening in Australia. The tool was validated using data from the 45 and Up Study, an ongoing cohort study of over 260,000 Australians aged 45 and older. Results showed PLCOm2012 predicted lung cancer incidence well and identified more high-risk individuals than the criteria used in the National Lung Screening Trial. Further modeling is still needed to fully assess the effectiveness and cost-effectiveness of using PLCOm2012 to target lung cancer screening in Australia.
ORIGINAL PAPERRisk of colorectal cancer among long-term ce.docxalfred4lewis58146
This study analyzed data from 64,507 cervical cancer patients in the SEER database from 1973 to 2009 to evaluate the risk of developing colorectal cancer after receiving radiation treatment. The results showed that after 8 years of follow up, patients who received radiation had double the risk of colon cancer compared to those without radiation (hazard ratio of 2.00). For rectal cancer, the risk diverged after 15 years, with a hazard ratio of 4.04 for those receiving radiation. By 35 years, the absolute risk of colon cancer was 6.5% for those receiving radiation versus 2.5% without, and 3.7% versus 0.8% for rectal cancer respectively. The risk of colorectal cancer did

- The Personalized OncoGenomics (POG) program at the British Columbia Cancer Agency conducted whole-genome analysis on tumors from 100 patients with advanced or incurable cancers to inform treatment decisions.
- Fresh tumor and blood samples were obtained from patients and underwent whole-genome and RNA sequencing. Computational analysis identified potential driver mutations, genes and pathways.
- A multidisciplinary team discussed genomic findings weekly and established guidelines for interpreting and communicating results to integrate them into patient care. Genomic findings were considered actionable in 55 of 78 cases that underwent whole-genome analysis, and motivated treatment changes in 23 cases.
- The experience demonstrated that a multidisciplinary team can implement an approach where whole-genome
Lung cancer remains a leading cause of cancer death. While early detection improves survival rates, past screening studies using chest x-rays and sputum analysis failed to reduce mortality. New screening methods using low-dose CT scans have shown promise in detecting early-stage cancers. However, limitations include high false positive rates and the need for improved methods to assess growth of small nodules over time. Further research is still needed to determine if lung cancer screening using low-dose CT can reduce mortality and be cost-effective.
Association between genomic recurrence risk and well-being among breast cance...Enrique Moreno Gonzalez

The Framingham Heart Study is a long-running cardiovascular cohort study that began in 1948 with over 5,000 residents of Framingham, Massachusetts. It found that smoking, high cholesterol, high blood pressure, obesity, and other factors increase risk of cardiovascular disease. The Nurses' Health Study began in 1976 and includes over 120,000 female nurses who complete biennial questionnaires. It has investigated links between oral contraceptives, diet, lifestyle and disease risks like breast cancer. A second Nurses' Health Study began in 1989 with younger nurses to further study these relationships.
kermack & mc kendrick epidemic threshold theoremMrinmoy Bharadwaz
Kermack and McKendrick developed one of the first epidemiological models in 1927 to study the transmission dynamics of communicable diseases that confer permanent immunity. Their simple SIR model divides a population into susceptible, infected, and removed compartments. It introduced the basic reproduction number (R0), which determines whether an outbreak occurs - if R0 is less than 1, the disease dies out, whereas if R0 is greater than 1, there is a single outbreak that increases then decreases. This model explained the rapid rise and fall of historical epidemics while making simplifying assumptions about population homogeneity and disease stages.
- This study followed women who booked home births in the UK in 1994 and matched them to similar women who booked hospital births.
- Outcomes were recorded for 5,971 home birth women and 4,724 matched hospital birth women. The groups were low-risk and well-matched.
- Planning a home birth was found to halve the chances of assisted or caesarean births compared to planning a hospital birth. Home births also had less reported high blood pressure and less stressful antenatal care.
- However, bias may exist since home birth women tended to be more educated/affluent and high-risk women who transferred care were excluded.
This document discusses Sir Richard Doll's landmark case-control studies from 1950 and 1990 that linked smoking to lung cancer. The 1950 study compared hospital patients with and without lung cancer and found heavy smokers were 50 times more likely to develop lung cancer. Subsequent national trends in the UK showed smoking rates halved between 1950-1990, while lung cancer rates fell more sharply, indicating risk declined for continuing smokers. However, those still smoking in 1990 had higher risks due to persistent smoking. The study concluded that stopping smoking, even in middle age, significantly reduces lung cancer risks, and stopping before middle age avoids over 90% of tobacco-related risk.
This document discusses case-control studies and their design and analysis. It begins by defining case-control studies as observational studies where subjects are sampled based on disease presence or absence and their prior exposure is then determined. It describes key features, need, steps in design including case and control selection. It then covers statistical analysis including odds ratios to measure risk associated with exposure and interpretations. It discusses effect modification and confounding, and analytical tools like stratification and multivariate modeling to control for confounding.
Non-sampling errors occur in surveys and censuses due to factors other than sampling and can happen at various stages:
- Specification errors occur during planning due to issues like incomplete population coverage or ambiguous questions.
- Ascertainment errors happen during data collection due to inaccurate recording or ambiguous instructions.
- Tabulation errors take place during analysis through mistakes in coding, analysis or presentation of results.
Some common sources of non-sampling errors include lack of proper planning, incomplete or inaccurate responses, ambiguous definitions, and errors in data processing. Measures like pre-testing questionnaires, hiring experienced staff, and cross-checking data can help reduce non-sampling errors.
This document discusses control charts for attributes known as p-charts or fraction nonconforming charts. It describes how to calculate control limits for p-charts using both known and unknown values of p. Sample size can be determined to ensure at least one nonconforming unit or to detect a specified level of process shift. Variable sample sizes and average sample sizes are approaches to determine control limits. Standardized control charts also allow comparison of points measured in standard deviation units. A disadvantage is these charts do not account for clustering of nonconforming units.
This document discusses control charts, specifically the C-chart. It defines a C-chart as a control chart used for nonconformities, or defects, in a product. A C-chart graphs the total number of nonconformities found in samples versus the sample number. It contains a central line at the expected value of defects (c) and upper and lower control limits at c ± 3√c. The document provides an example of constructing a C-chart using sample data and outlines how C-charts can be used in healthcare processes to monitor quality.
This document provides an introduction to X-charts, which are a type of control chart used in statistical quality control. X-charts monitor the mean of a process to determine if it is in statistical control. The document outlines the basic components of an X-chart, including the center line, lower control limit, and upper control limit. It describes how to calculate the control limits based on whether the mean and standard deviation are known or estimated. Various criteria for detecting when a process is out of control based on the X-chart are also presented, along with examples of different types of shifts and patterns that could indicate issues like shifts, trends or cycles in the process mean.
Control charts consist of three horizontal lines: a central line showing the process average, an upper control limit, and a lower control limit. Variables are quality characteristics that can be measured and expressed quantitatively. An R chart plots sample ranges to control variability within subgroups. To set up an R chart, sample ranges are plotted against sample number, with upper, central, and lower control limits calculated using constants D3 and D4 that depend on sample size.

Suzanne Lagerweij - Influence Without Power - Why Empathy is Your Best Friend...Suzanne Lagerweij
This is a workshop about communication and collaboration. We will experience how we can analyze the reasons for resistance to change (exercise 1) and practice how to improve our conversation style and be more in control and effective in the way we communicate (exercise 2).
This session will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
Abstract:
Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

2. ATOMIC BOMB CASUALTY COMMISSION
HIROSHIMA AND NAGASAKI
A case-control study in
Hiroshima and Nagasaki
examining non-radiation
risk factors for thyroid
cancer.
11. BACKGROUND:
Because little is known about the aetiology
of thyroid cancer in Japan, we conducted a
case-control study of thyroid cancer and
lifestyle and other risk factors. The present
report focuses on medical history, family
history, smoking and alcohol drinking, and
their interactions with radiation exposure.
12. METHODS:
Thyroid cancer cases reported to the Hiroshima and
Nagasaki tumour registries during 1970-1986 were
histological reviewed by pathologists. For each of 362
cases with papillary or follicular adenocarcinoma
diagnosed at <75 years of age, one control without
cancer matched on city, sex, year of birth, and atomic-
bomb radiation exposure was selected from the Life
Span Study cohort or the offspring cohort. The cohort
subjects were residents of Hiroshima and Nagasaki with
or without atomic-bomb radiation exposure.
Information on risk factors was obtained through a pre-
structured interview carried out in 1986-1988.
13. RESULTS:
Analysis using conditional logistic regression showed
history of goiter or thyroid nodule and family history of
cancer to be significantly associated with an increased
odds ratio for thyroid cancer. Smoking and alcohol
drinking were significantly and independently
associated with a reduced odds ratio. Interaction
between smoking and alcohol drinking was not evident
based on either an additive model or a multiplicative
model. Radiation exposure did not significantly modify
the associations between these factors and thyroid
cancer risk.
14. CONCLUSION:
History of goiter/nodule and family
history of cancer were risk factors for
thyroid cancer. Smoking and alcohol
drinking were independently associated
with reduced risk. Self-reported
retrospective information presents some
limitations in interpretation of the data
