This document provides an overview of radical cholecystectomy for gallbladder cancer. Some key points: - Radical cholecystectomy involves removal of the gallbladder and a rim of liver tissue, often including segments IVb and V. It aims to achieve clear margins and may include bile duct resection and lymph node dissection. - Gallbladder cancer has a poor prognosis due to late presentation and aggressive spread. Risk factors include gallstones, inflammation and older age. Diagnosis involves ultrasound, CT, MRI and biopsy. - Staging is according to TNM classification. Surgery with radical cholecystectomy offers the only chance of cure, but outcomes remain poor even with resection due to high rate

5. Etiology
 Prevailing theory: chronic inflammation with subsequent cellular
proliferation
 Risk factors:
o Gallstones
o Choledochal cyst
o Primary sclerosing
cholangitis (PSC)
o Anomalous
Pancreaticobiliary Junction
(APBJ)
o Old age
o Typhoid carrier/H. pylori
infection

6. Pathology
 Adenocarcinoma: 80-90%
oPapillary
oNodular
oTubular
 Squamous cell carcinoma
 Adenosquamous cell carcinoma
 Oat cell carcinoma
 Anaplastic carcinoma

7. Pattern of spread
 Via lymphatics
 Via venous drainage
 Direct invasion into liver parenchyma
At the time of diagnosis:
o 25% localized to GB
o 35% regional node involvement/ extension into adjacent liver
o 40% distant metastasis

8. Clinical Presentation
 90% originate from fundus or body: produce symptoms in advanced stage
 Early invasive GBC: asymptomatic or non-specific symptoms that mimics
cholelithiasis or cholecystitis
 Symptomatic: RUQ pain, abdominal discomfort, nausea, vomiting, anorexia
 Advanced GBC: malaise, weight loss, jaundice, abdominal mass, ascites
 Palpable GB on physical examination: Courvoisier’s Sign

9. Diagnostic evaluation
Ultrasound:
Suspicious findings:
oSolitary or displaced stone, mural thickening or calcification, mass
protruding into the lumen, fixed mass in GB, loss of interface between
GB and liver, direct liver infiltration
Overall accuracy limited
Sensitivity 70-100% 1

11. Computed Tomography (CT) scan:
For pt. with US-detected GB lesion/ incidentally diagnosed GBC
following simple cholecystectomy
Sensitivity: 71%, specificity: 92% 1
CT findings:
oPolypoid mass protruding into the lumen/completely filling it,
focal/diffuse thickening of GB wall, mass in GB fossa with GB being
indiscernible, liver invasion, suspected nodal involvement, distant mets
oGBC complicated with simple cholecystitis: higher frequency of LN
enlargement, more-extensive wall thickness, focal irregularity in wall
thickness, less distention of GB

12.  Features of advanced disease include:
o Intrahepatic biliary dilatation
o Invasion of adjacent structures
o Lymphadenopathy
o Peritoneal carcinomatosis
o hepatic and other distant metastases

13. Magnetic Resonance Imaging (MRI):
 Reliable in staging of advanced GBC
 MRI + MRCP: sensitive in detection of obstructive jaundice, liver
invasion and hepatic/LN metastasis
 Difficult to delineate invasion into duodenum or omental mets
 Sensitivity for hepatic invasion 100%, LN invasion 92% 1

imaging with MR cholangiopancreatography. Journal of Computer Assisted Tomography, 26(3), 405–410

14. Endoscopic ultrasound (EUS):
 To access the depth of tumor invasion into the wall of GB
 To define LN involvement in porta hepatis and peripancreatic regions
 Means to obtain bile for cytologic analysis:
o73% sensitivity for diagnosis of GBC1
 EUS guided FNA for FB mass
 Specificity: 92%, specificity 88% 2

15. Laboratory studies:
 Non diagnostic
 Elevated liver enzymes: serum bilirubin, ALP
 Tumor markers: carcinoembryonic antigen (CEA) or carbohydrate
antigen(CA) 19-9
For staging evaluation:
 Chest X-ray/CT
 PET-CT

16. Staging systems
1) Modified Nevin System (Donohue et.al. 1990, Nevin et.al. 1976)
2) Japanese Biliary Surgical Society System (Onoyama et.al. 1995)
3) AJCC/UICC TNM staging system (Beahrs and Myers 1983)

17. Tumor, Node, Metastasis (TNM) staging 1

20. Management
Resection remains the only potential for cure
oSimple cholecystectomy
oRadical (Extended) cholecystectomy
oBile duct resection
oHepatic resection
oLymph node dissection
oLaparoscopic port site resection

21. Radical Cholecystectomy
 En bloc removal of gall bladder with a rim of at least 2 cm adjacent
gall bladder bed
 Formal central liver resection (segments IVb and V) may be
appropriate depending upon the location of tumor (fundus, body,
neck)
 Laparoscopic vs open surgery?
oWullstein, C., Woeste, G., Barkhausen, S., Gross, E., & Hopt, U. T. (2002). Do
complications related to laparoscopic cholecystectomy influence the
prognosis of gallbladder cancer? Surgical Endoscopy, 16(5), 828–832

gallbladder cancer: The glass is one-third full. Archives of Surgery (Chicago,
Ill.: 1960), 145(2), 133

23. Extent of liver resection: wedge vs segment IVb/V

24.  In some cased it involves resection of
o Entire liver lobe (hepatic lobectomy)
o Suprapancreatic segment of extrahepatic
bile duct (bile duct resection)
o Regional LN dissection in an En bloc
fashion.
 Main difference between this procedure
and original radical cholecystectomy
described by Glenn et.al compromise
the extent of regional
lymphadenectomy and presence or
absence of bile duct resection.
Fig. Extended" radical cholecystectomy for gallbladder
cancer. The dashed line indicates the scope of wedge
resection. The double-headed arrows indicate lines of
division of the extrahepatic bile duct. The pale blue area
indicates the extent of regional lymph node dissection

25. Bile duct resection
 Tumor extending into CBD or negative cystic duct margin (via frozen
section) can’t be achieved: extrahepatic bile duct resection should be
performed
 Reconstruction with Roux-en-Y hepaticojejunostomy
 Some recommends routine excision of extrahepatic bile duct as a mean of
achieving more complete lymphadenectomy
 When ducts compromised during skeletonization of porta hepatis:
resection and reconstruction is warranted

26. Fig. Roux-en-Y hepaticojejunostomy with biliary stent placement to reduce stricture at
the anastomosis

27. Inter aortocaval LN sampling
 Interaortocaval (16b1) LN involvement in GBC: sign of advanced
disease with a dismal prognosis equivalent to that of distant
metastasis
 CT indicator (size >10 mm and heterogeneous internal architecture) of
16b1 LN
oBut positive predictive value is less
 That’s why detection of 16b1 LNs, intraoperative biopsy and frozen
section analysis of these nodes have been proposed 1

28. Lymph node dissection
 Indicated whether or not bile duct resection is performed if GBC >T1a
 LN mets found in 35-80% with tumors invading perimuscular connective tissues(≥T2) 1
 More reliable predictors of poor outcome after surgery
o 5-yr survival: 57% without vs 12% with LN metastases2
 Involves removal of all LN in porta hepatis and along hepaticoduodenal ligaments
including those of cystic duct, CBD, hepatic artery and portal vein

30. Standard lymphadenectomy

31. Lymph node dissection cont.
 At least 6 LNs should be removed for proper staging 1
 Number of metastatic LN and LN ratio are more prognostic than
location of metastatic LN
1 Zhu AX, Pawlik TM, Kooby DA. et al. Gallbladder. In: AJCC Cancer Staging Manual, 8th, Amin MB (Ed), Springer 2017. p.303

32. Hepatic resection
 Either margin-negative resection with at least 2cm non-anatomic wedge resection of GB fossa OR
anatomic wedge resection of segment IVb and V 1
 Tumors of fundus and body of GB: far from the inflow structures of liver
 Various resection margins proposed: ranging from 1-5 cm 2
 No data to showing benefit for anatomic resection of segments IVb and V with localized diseases 3
 Anatomic resection: reduces risk of bleeding and bile leakage 4

cancer. World Journal of Surgical Oncology, 5, 55

33. Hepatic resection cont.
 Veins from GB drain into middle hepatic vein via cholecysto-hepatic
veins 1
 Direct lymphatic drainage into liver has also been demonstrated 1
 More aggressive surgery like extended right hepatectomy for tumor
infiltration into segments IV, V and VII
1 Misra, M. C., & Guleria, S. (2006). Management of cancer gallbladder found as a surprise on a resected gallbladder specimen. Journal of Surgical Oncology, 93(8), 690–698

34.  Conclusion: Tumor biology and stage, rather than extent of resection, predict
outcome after resection for gallbladder cancer. Major hepatic resections,
including major hepatectomy and CBD excision, are appropriate when
necessary to clear disease but are not mandatory in all cases.

35. Laparoscopic port site resection
 Laparoscopic manipulation doesn’t diminish the survival of patients with
incidentally found GBC 1
 Some recommend port site excision at the time of reexploration after lap
cholecystectomy 2
 Radical resection doesn’t require resection of previous port sites 3
 Tumor found in previous port site is a marker for disseminated peritoneal
disease
 Thus removal of port site will not be curative 4

37. Surgery for Gall bladder cancer
Accurate staging of the disease
Proper patient selection & surgical planning
Identifying patient who would or would not benefit from surgery
oDetect metastatic disease (US, CT, MRI, PET)
oLocoregionally advanced disease (resectability?/need for downstaging)
Avoiding non-therapeutic laparotomy
oStaging laparoscopy
oAdvanced extended laparoscopic staging

38. Unresectable disease
Absolute contraindication to resection:
 Liver mets
 Peritoneal mets
 Malignant ascites
 Tumor involvement of paraaortic, paracaval, SMA and/or Celiac artery LN
 Extensive involvement of hepaticoduodenal ligament by tumor either directly or through LN
involvement
 Encasement or occlusion of major vessels (common hepatic artery or main portal vein) by tumor

39. Unresectable disease cont.
Relative contraindication to resection:
 Pre-operative jaundice in fundus based GBC
 Perihilar-type GBC arising from infundibulum or cystic duct

40.  Identifies metastatic disease or other findings that contraindicate
tumor resection 1
 Recommended prior to laparotomy for all suspected or proven GBC
>pT1b 2
 Use of two ports avoid missing detectable lesions

prospective study to evaluate the role of staging laparoscopy in the management of gallbladder cancer. Annals of Surgery, 258(2), 318–323

41. Staging laparoscopy cont.
A prospective study of primary GBC
patients between May 2006 and
December 2011: Of the 409 primary GBC
patients who underwent SL, 95 had
disseminated disease [(surface liver
metastasis (n = 29) and peritoneal
deposits (n = 66)]. The overall yield of SL
was 23.2% (95/409)

42. Staging laparoscopy cont.
Discussion: Disseminated disease is relatively uncommon in patients with IGBC and
SL provides a very low yield. However, patients with poorly differentiated, T3 or
positive-margin gallbladder tumors are at high risk for Disseminated Disease and
targeting these patients may increase the yield of SL

43. Resectable disease
Early T stage disease: tumors confined to the wall of GB (ie,
stage 0, I or II; Tis, T1 or T2)
Tumors extending beyond the mucosa (ie, T1a): better
outcomes with more radical surgery 1

review. Scandinavian Journal of Gastroenterology, 52(5), 505–514

44. T1a:
oTumors limited to lamina propria
oCystic duct margin negative
oSimple cholecystectomy alone is adequate 1
oCure rate: 73-100% 1
oRe-resection for T1a tumors doesn’t appear to provide an
overall survival benefit 2

838

45. T1b:
 Tumor invades muscular layer
 Optimal approach is controversial, Pt benefit from more radical approach
 Higher incidence of LN metastases compared to T1a (15% vs 2.5%) 1
 High loco-regional recurrence 50-60%
 High rates of liver involvement 0-13%
 Median survival advantage >3 yrs: extended vs simple cholecystectomy 2
o 9.85 vs 6.42 years

46.  Method: Retrospective cohort study from the National Cancer Data Base
(2004-2012) with non-metastatic T1b GBC
 Conclusion: <50% of the patients with a T1b GBC primary tumor undergo
the recommended surgical treatment. Given that 15% of these patients
have nodal metastasis and in light of the previously described benefits of
adjuvant therapy for node positive GBC, failure to perform RC-RL risks
incomplete staging and thus undertreatment for patients with T1b GBC.

47. T2:
 Invades the peri muscular connective tissue on the peritoneal side, without
involvement of serosa
 Extended cholecystectomy is indicated 1
 High chance of residual disease 40-76%
 High chance of liver 2 (10%) and LN 3 (30-60%) involvement
 High rates of local recurrence after simple cholecystectomy

48.  Subdivided depending on the invasion site into:
o T2a (peritoneal)
o T2b (hepatic)
 T2b has worse prognosis
 Extended cholecystectomy should be mandated in pt with T2b (hepatic)
but not T2a (peritoneal) disease 1
 This approach, however is not universally accepted
o Standard of care: extended cholecystectomy for all resectable T2 disease 2

49.  Survival in patient with T2 lesion is related to the number of LN
removed 1
 5 yr survival is 24-40% without resection and may approach to 80-100
after re-resection 2

cholecystectomy for accidentally undiagnosed gallbladder carcinoma. World Journal of Surgery, 27(3), 266–271

50. Locally advanced and node positive disease
 In past because of overall poor prognosis: surgeons were reluctant to
perform surgery 1
 Support for radical surgery with reports indicating long term survival
in pt with T3 and T4 tumors, 15 to 63% and 7 to 25% of pt
respectively 2

51.  Some groups advocate even more extensive resection:
oHepatectomy, pancreaticoduodenectomy, colectomy and nephrectomy
 Medial survival of 17mths, 2% mortality rate 1
 But morbidity and mortality rates are high (48 to 54% and 15 to 18%
respectively)
 Study of 79 major hepatectomies had longer survival 32 mths as
compared to 10 mths for major hepatectomies +
pancreaticoduodenectomy 2

for advanced gallbladder cancer. The British Journal of Surgery, 106(5), 626–635

52. T3:
 Tumor invades through serosa
 Extended cholecystectomy en bloc with involved adjacent organ
Conclusion: Tumor biology and stage, rather than extent of resection, predict
outcome after resection for gallbladder cancer. Major hepatic resections, including
major hepatectomy and CBD excision, are appropriate when necessary to clear
disease but are not mandatory in all cases

53. T4:
 Invades main portal vein, hepatic artery and adjacent extrahepatic
organs
 Generally locally unresectable
 Curative resection in selected patient with stage IVa disease (T4, N0-
1,M0)

54. Node positive:
 Tumor involvement of locoregional LN: 5-yr survival rate - 28-60%
with radical resection 1
 Radical lymphadenectomy results are less favorable of nodal disease
beyond hepatoduodenal ligament, posterosuperior
pancreaticoduodenal area and along common hepatic artery 1
 FNA +ve tumors: surgery done for palliation of specific problems

55. Managing incidental GBC found on pathology
 Incidental GC: 0.25-1.5% of pt undergoing lap chole 1
 Should undergo staging evaluation with imaging modalities
 Management depends upon the disease extent (T stage)
 If the T stage of resected, incidental GBC is T1b, T2 or T3: surgical
reeploration and re-resection

year experience at memorial sloan-kettering cancer centre(Mskcc). Journal of Surgical Oncology, 98(7), 485–489

56. Optimal timing of re-resection:
 Reoperations between 4th-8th week from original cholecystectomy
had better overall survival 1
o4 weeks: 23.7 mths, 8 weeks: 26.6 mths
 Due to reduced inflammation and full appreciation of subclinical
disease (compared with reoperating <4 week) but does not allow too
much time for disease dissemination

Scoggins, C., Shen, P., Mogal, H. D., Schmidt, C., Beal, E., … Maithel, S. K. (2017). Association of optimal time interval to re-resection for incidental gallbladder cancer with overall
survival: A multi-institution analysis from the us extrahepatic biliary malignancy consortium. JAMA Surgery, 152(2), 143–149

58. Managing incidental GBC intraoperatively
 Surgeon should maintain high index of suspicion in pt with risk factors
 If obvious malignant lesion encountered: best not to sample the
lesion laparoscopically to reduce the hazard of seeding
 Procedure should be converted to open resection, of resection will be
undertaken
 Completing the cholecystectomy and obtain frozen section, if
positive: extended cholecystectomy

59.  To compare patients with gallbladder cancer presenting for therapy
with and without prior operation elsewhere to determine if an initial
noncurative procedure alters outcome
 Mortality, complication, and long-term survival were the same

60.  The scoring model to predict IGBC includes age, female gender, previous
cholecystitis, and either jaundice or acute cholecystitis
 The scoring system was applied to three risk-groups, based on the risk of having
IGBC, eg. the high-risk group (>8 points) included 7878 patients, with 154
observed and 148 expected IGBC cases.

61. Bile spillage
 Association with incomplete resection and systemic recurrence
When GB cancer is suspected during LC conversion to open surgery for
preventing bile spillage and achieving curative resection should be
considered

62. Laparoscopic radical surgery
 Traditionally, Laparoscopic surgery not routinely recommended in
non-incidental setting
 Recent studies suggest equivalent outcomes between laparoscopic
and open approaches
 Robotic-assisted procedures have also been described and are carried
out

64. Adjuvant therapy
 Despite conflicting data, limited level I data
 Currently, Gemcitabine-based regimens, often combining with platinum agent:
common choice for treating GBC
 Gemcitabine shown to improve median overall survival (9.5 months) 1
 Japanese multi-institutional trial: randomized resection f/b adjuvant mitomycin
and 5-FU vs resection alone2
o 5-yr survival 20.3% vs 11.6%

65.  Most recently, Phase II trial: combination of Gemcitabine,
Capecitabine and radiation therapy in pt with extrahepatic biliary
tract and GBC showed promising results 1

gallbladder carcinoma. Journal of Clinical Oncology: Official Journal of the American Society of Clinical Oncology, 33(24), 2617–2622

66. Neoadjuvant therapy
 Provide opportunity to determine biologically aggressive tumors who
may not benefit from extensive operation
 Small case series suggest: Gemcitabine-Platinum based combinations
have some role 1
 Recent study from MD Anderson Cancer Center: retrospective review
of their GBC resected with wide 1-cm negative margin and received
either neoadjuvant or adjuvant therapy: 5-yr survival 50.6%

advanced gall bladder cancer. Future Oncology (London, England), 11(8), 1191–1200

67.  Adjuvant therapy showed not improvement in survival, and
neoadjuvant treatment had only served to significantly delay time to
operation

68. Palliative procedures
 Palliation for jaundice, upper abdominal pain and symptoms of biliary
obstruction
 Methods:
• Simple cholecystectomy
• Endoscopic or percutaneous biliary drainage
• Endoscopic stenting or intestinal bypass
• Biliary bypass:
• Patient who can tolerate surgery
• Recurrent obstruction
• Segment II cholangiojejunostomy and staying away from the hepatoduodenal
ligament, the most common site of disease progression, successfully palliated the
majority of patients 1

gallbladder. The British Journal of Surgery, 83(12), 1709–1711

69. Prognosis
 5 year survival of all pt with GB cancer: <5%
 Median survival of 6 mths
 T1 treated with cholecystectomy: 85%-100%, 5 year survival
 T2 treated with extended cholecystectomy vs cholecystectomy: >70% vs 25%-
40%
 Advanced disease with resectable GB: 5 year survival of 20%
 Median survival of pt with distant mets: 1-3mths

70. Prognosis cont..
 Non-specific symptoms and advanced stage of disease at
presentation: poor outcomes
o5-yr survival rate: 5-12%
 Recurrence after resection : commonly Liver or celiac/retro pancreatic
nodes
 Prognosis for recurrent disease: poor
 Death commonly d/t biliary sepsis or liver failure
