    • Planned for NACT i/v/o liver metastases
      FNAC (ultrasound guided) of the right adnexal mass was done:
      A-2829/11: malignant tumour- cellular mild pleomorphism,
      s/o possibly malignant epithelial ovarian tumor
      However, possibility of sertoli cell tumour cannot be ruled out.
    • Taken up for staging laparotomy with TAH with BSO
      Midline vertical incision extended supra - umbilically
      Abdomen opened
      Ascites was present- fluid was taken for peritoneal cytology
      18 X 12cm mass seen arising from the left ovary
      Adhesions present between the sigmoid colon and the tumor mass were separated.
    • Breach in the serosa of sigmoid colon was sutured
      TAH with BSO was done
      Right tube and ovary were normal
      Pelvic peritoneum was indurated
      Omental cake present – infracolic omentectomy done
      Residual disease :
      Small 1cm deposits over left cardinal ligament
      Abdomen closed in layers
    • Parts of urine output was blood tinged.
      Intra op cystoscopy done- b/l ureteric orifice seen urine reflux seen.
      1 unit blood transfusion was given intra-op.

    • PERITONEAL CYTOLOGY(2092/11): No malignant cells seen
      MICROSCOPICALLY: tumour arranged in the form of solid nests, islands and focally in tubules with fine fibro vascular septa.
      Tumour cell are mildly pleomorphic with fine granular chromatin and moderate amount of granular eosinophilic cytoplasm.
      Left ovary – Neuroendocrine carcinoma
      Right ovary – metastasis present
      Uterus, cervix and B/L fallopian tubes – free of tumour
      Omentum – tumour deposits
      Neuroendocrine tumors of ovary
      I Growth limited to the ovaries
      Growth limited to one ovary;
      no ascites present containing malignant cells;
      no tumor on the external surfaces;
      capsule intact
      Growth limited to both ovaries; no ascites
      present containing malignant cells;
      no tumor on the external surfaces;
      capsules intact
      Tumor stage Ia or stage Ib but with tumor on the surface of one or both ovaries;
      Or with capsule ruptured;
      Or with ascites present containing malignant cells or with positive peritoneal washings
    • II Growth involving one or both ovaries with pelvic extension
      Extension and/or metastases to the uterus and/or tubes
      Extension to other pelvic tissues
      Tumor stage IIa or stage IIb but with tumor on the surface of one or both ovaries;
      Or with capsule(s) ruptured;
      Or with ascites present containing malignant cells
      Or with positive peritoneal washings
    • III Tumor involving one or both ovaries with peritoneal implants outside the pelvis and/or positive retroperitoneal or inguinal nodes; superficial liver metastasis equals stage III; tumor is limited to the true pelvis but with histologically verified malignant extension to small bowel or omentum
      IIIa Tumor grossly limited to the true pelvis with negative nodes with histologically confirmed microscopic seeding of abdominal peritoneal surfaces
      IIIb Tumor of one or both ovaries; histologically confirmed implants of abdominal peritoneal surfaces, none exceeding 2 cm in diameter; nodes negative
      IIIc Abdominal implants 2 cm in diameter and/or positive retroperitoneal or inguinal nodes
    • IV
      Growth involving one or both ovaries with distant metastasis;
      if pleural effusion is present, there must be positive cytological test results to allot a case to stage IV;
      parenchymal liver metastasis equals stage IV
    • Carcinoid/ Neuroendocrine tumors
      Classified under Germ cell neoplasms of 0vary which comprise of
      Germ cell tumors
      Endodermal sinus tumor
      Embryonal carcinoma
    • Teratoma
      Immature (solid, cystic, or both)
      • Solid
      Mature cystic teratoma (dermoid cyst)
      Mature cystic teratoma (dermoid cyst) with malignant transformation
      Monodermal or highly specialized
      Struma ovarii
      Struma ovarii and carcinoid
    • Mixed forms (tumors composed of types A–F in any
      possible combination)
    • Carcinoid of the ovary
      Primary Carcinoid tumors of ovary account for less than 5% of all Carcinoid tumors.
      And for less than 0.1% of all ovarian neoplasms.
      Are typically localized (89%)
      Nearly all primary ovarian neoplasms are unilateral
    • The tumours are typically classified as germ cell tumors of the ovary and can be divided into four categories:
    • Primary Carcinoid tumors typically behave in a benign fashion.
      Most ovarian carcinoids contain the insular pattern, are unilateral and early stage.
      It is important to establish that these are not metastatic carcinoids.
      Insular followed by trabecular are the most common subtypes that metastasize to ovary.
    • Given the rarity of the disease, it is also critical to rule out a metastatic GI Primary that could have metastasized to ovary and tend to present as bilateral ovarian metastases.
      The constipation and hirsutism are thought to be due to the release of peptide YY(PYY) by the tumors.
    • The majority of women with primary ovarian Carcinoid tumours are found incidentally on cross sectional or ultrasound imaging.
      Rarely, they may also present with abdominal pain, constipation, hirsutism, and a pelvic
    • For women who present with a stage I primary ovarian carcinoid, the prognosis is excellent, with greater than 90% survival.
      Women with more advanced diseased, the prognosis poor. (Octreotide has been used in some reports)
      Most common type of ovarian carcinoid.
      Occurring in patients with between 40 & 80 years of age.
      Majority present with a pelvic mass and approximately 40% will have clinical evidence of carcinoid syndrome.
      Those presenting with carcinoid syndrome have larger masses(>7cm).
      It is important to differentiate a primary lesion from a ovarian metastases.
    • Typically slow growing.
      For those limited to the ovary, the 10 yr survival 100%(if unilateral)
      With advanced stage disease, the 5-year survival is 33%.
      Second most common
      In women 30 – 70 years of age.
      Not typically associated with carcinoid syndrome, but may be associated with constipation due to PYY.
      No reported tumor related deaths
      Occur in patients between 30 and 80years of age
      Tumors may be pure or may be associated with mature cystic teratomas.
      One need to consider that the ovarian tumor may be a metastasis from gastrointestinal tumor.
      In mucinous carcinoid, an appendicectomy should be performed to exclude the more common primary mucinous appendiceal carcinoid.
      Overall survival good
    • Management
      The most recent Neuroendocrine tumor NCCN guidelines recommend that the tumor be removed completely with the goal of attaining negative margins.
      If the diagnosis is known or suspected pre-operatively, Octreotide (100-500mcgSQ/IV every 6 – 12h) be administered immediately prior to or during resection to avoid carcinoid crisis.
      In ovarian carcinoid tumors, fertility sparing surgery is permissible as these tumors are generally unilateral and associated with a good prognosis.
      But can include radical debulking surgery dependent on patients age and disease distribution.
    • Most common metastatic sites include regional lymph node, liver, bone and lung.
      Most demonstrate a remarkable tropism for the liver.
      Liver lesions should be considered for resection to control tumor burden and
      NCCN guidelines recommend that those lesions that are not resectable should be considered for cryotherapy, radiofrequency ablation, or regional embolisation.
    • Role of adjuvant therapy
      No evidence to support the use of either hormonal, chemotherapy or radiation therapy for gynecological carcinoid tumours.
    • Advanced stage or Recurrent disease
