Intratumoral Teffs represented functionally active subsets of both TH1 and TH2 that were not anergic but were suppressed by multiple Treg subsets, which comprised FOXP3 + Tregs and Tregs secreting transforming growth factor β1 and IL-10. These results imply that the microenvironment of cervical carcinomas harbored both TH1 and TH2 subsets of CD4 Teffs that were functionally active but were perhaps unable to perform because of the overpowering effect of Tregs.

Thirty-three patients with germ cell tumor of the ovary were seen at Kidwai Memorial Institute of Oncology (KMIO), Bangalore, between 1996 and 1999. Twelve patients had endodermal sinus tumor (EST), 11 dysgerminoma, seven mixed germ cell tumor, and three immature teratoma. Thirteen patients had bulky residual disease of >10 cm after the primary surgery. All but one patient received a combination of bleomycin, etoposide, and cisplatin (BEP) either as neoadjuvant (NACT, 3 cases) or as adjuvant therapy (28 cases). In the present study, all 11 patients with dysgerminoma achieved sustained complete remission (CR), irrespective of the size of residual disease at the time of chemotherapy. Four out of six cases (66.6%) with bulky nondysgerminomatous tumor achieved CR, which was sustained in three cases and one recurred. Fifteen of the remaining 16 (93.7%) nonbulky, nondysgerminomatous tumors achieved CR, which was sustained in 14 cases and recurred in one. This study indicates that there may be a role for aggressive cytoreductive surgery, either primary/interval or at the time of second-look laparotomy, in selected patients with nondysgerminomatous germ cell tumor of the ovary.

Primary peritoneal serous carcinoma (PPSC) is a rare malignancy that arises primarily from peritoneal surface epithelium. However there are limited studies on these tumors even in world literature. To study the clinical, pathologic profile, outcome and prognostic features of PPSC. A 5 year retrospective study of PPSC diagnosed and treated at our centre was conducted. The pathological specimen of PPSC diagnosed from January 2008 to December 2012 were reviewed by gynaeconcopathologists. The diagnosis was based on GOG criteria, complemented with IHC. Majority of the patients underwent upfront de-bulking surgery. Postoperatively, six cycles of combination chemotherapy with paclitaxel (175 mg/m 2 ) and carboplatin (AUC 6) was administered every 3 weekly. These patients were analysed for progression free survival (PFS), this was correlated with stage and surgical adequacy. The median age of presentation was 56 years. The total number of ovarian cancers treated during study period was 374. The 30 cases were clinically suspected to have primary peritoneal carcinoma (PPC) on pre-and intraoperatve gross findings, but further evaluation with histopathological examination, IHC and GOG criteria revealed only 10 cases were genuine PPSC. The remaing 20 cases; 13 were found to poorly differentiated ovarian carcinomas, six were primary fallopian tube carcinoma and one was appendicular carcinoma. The 10 (2.7 %) cases of the 374 were eligible for the PPSC analysis. The two (20 %) of the 10 cases had family history of breast and ovarian cancers, two (20 %) cases were diagnosed as abdominal tuberculosis (TB) prior referral to our centre. Radiological presentation includes gross ascites, with omental caking and normal adenexa. The eight (80 %) of 10 cases presented with stage IIIC and other two cases (20 %) with stage IV disease. The eight (80 %) of 10 cases underwent upfront surgery; six (75 %) of these eight cases had optimal cytoreduction, i.e. residual disease (RD) <1 cm or no visible disease (R0) and other two (25 %) suboptimal cytoreduction. The two (20 %) of 10 cases with stage IV disease received neoadjuvant chemotherapy (NACT) followed by interval cytoreduction. After debulking surgery the most useful IHC marker include CK7+, CK20-, CA125+, WT-1+, and GCDFP-. At median follow up of 24 months (range 3-60 months), the median progression free survival (PFS) was 22 months, while the estimated 5 year PFS was 18 %. Stage IV disease and suboptimal surgery had poor outcome. The PPSC presents with advanced stage disease and are observed to be misdiagnosed abdominal TB in tropical countries. The GOG criteria and IHC complement the diagnosis. These have poor outcome despite optimal care, highlighting need for larger studies on this disease.
