Advanced epithelial ovarian carcinoma in Thai women: should we continue to offer second-look laparotomy?

OBJECTIVE: To determine survival among patients with epithelial ovarian carcinoma (EOC) who underwent a second-look laparotomy (SLL) and those refusing the procedure. Also to analyze factor(s) influencing the survival of the patients. METHOD AND MATERIAL: Medical records were reviewed of patients with advanced EOC who were clinically free of disease after primary surgery and platinum-based chemotherapy between January 1, 1992, and December 31, 1998. All of them were offered SLL. Measurement outcomes include patient survival and disease-free survival. RESULTS: There were 50 patients with clinically complete remission after chemotherapy. Sixteen patients underwent SLL, and thirty-four patients refused the procedure (NSLL). Seven patients (43.8%) were reported to have positive SLL. After the median follow-up time of 35 months, 12 patients had died, and 5 patients were lost to follow-up. The median survival time for patients with SLL was about 60 months. Five-year survival rates of patients in the SLL, and NSLL groups were 37 per cent (95%CI = 7%-69%), and 88 per cent (95%CI = 65%-96%) respectively (P<0.001). The median time to relapse was about 25 months for patients with negative SLL. Five-year disease-free survival rates of patients in the negative SLL, and NSLL groups were 28 per cent (95%CI = 4%-59%), and 54 per cent (95%CI = 34%-70%) respectively (P=0.251). By Cox regression analysis, tumor grade was the only significant prognostic factor influencing patients' survival (HR = 6, 95%CI of HR = 1.2-34.2). CONCLUSION: The second-look laparotomy doesn't have a favorable impact on overall and disease-free survival. Tumor grade is the only independent prognostic variable for survival of the patients.

Recent management of malignant ovarian germ cell tumors: a study of 34 cases.

OBJECTIVE: To review the outcome of the treatment in patients with malignant ovarian Germ cell tumors with respect to survival and surgical management at a single institution during 1990-1996. METHODS: Thirty-four patients with malignant ovarian Germ cell tumors were studied retrospectively for their surgical management. Fourteen patients had pure dysgerminoma, 11 endodermal sinus tumor, 6 immature teratoma, and 3 mixed Germ cell tumors. Nine patients had stage IA, 8 stage IC, 2 stage IIC, 8 stage III, 3 stage IV, and 4 referred patients with recurrent diseases. RESULTS: Nineteen patients underwent primary conservative surgery, 11 had primary nonconservative surgery. Twenty-two patients were treated with chemotherapy (BEP or EP or PVB regimen). Five patients with pure dysgerminoma received adjuvant radiotherapy. Persistent remission was achieved in 26 patients. Two patients (7.4%) had recurrence after remission. Seven patients had died of the diseases. Patients with complete clinical remission did not undergo second-look surgery. The overall survival was 78.8%, 100% for immature teratoma, 84.6% for pure dysgerminoma, 72.8% for endodermal sinus tumor, and 33.3% for mixed Germ cell tumors, with median follow-up time 31 (3-93) months. CONCLUSION: Patients with limited diseases regardless of histologic types can be safely managed by unilateral salpingo-oophorectomy followed by, if indicated, 3-4 courses of cisplatin-based chemotherapy. For advanced diseases, conservative surgery is advisable in patients with endodermal sinus tumor.

An HIV-infected woman with choriocarcinoma presenting with a nasal mass.

Gestational choriocarcinoma metastasized to the nasal mucosa is extremely rare. An HIV-infected woman with choriocarcinoma presenting with a nasal mass is reported. The clinical findings are compared with a previous reported case. She responded to multiagent chemotherapy and has obtained complete remission. The role of HIV infection is also discussed.

Epithelial ovarian cancer treated by platinum or platinum analogue with cyclophosphamide: experience in Ramathibodi Hospital.

This study presented the outcome of 92 EOC patients treated by platinum or platinum analogue with cyclophosphamide from January 1, 1993 to December 31, 1995. There were 77 evaluable patients. The follow-up ranged from 4-42 months (median 14 months). The over all 3-year survival was 64 per cent and the median progression-free interval was 16 months for the whole group. There was no significant difference in survival between patients who received cisplatin and those who received carboplatin (P = 0.093). Patients who underwent optimal debulking surgery had significantly longer progression-free interval (P = 0.001) than those who had sub-optimal surgery. Fifty four per cent of patients with clear cell carcinoma died of the disease. Patients who received cisplatin had a drop out rate while on therapy more often (24% vs 5.3%) than that of carboplatin. Toxicities from chemotherapy were moderate but manageable.

A randomized study comparing suture with non-suture cold-knife conization.

OBJECTIVE: To compare the short-term outcome of cold-knife conization between suture and non-suture (with Monsel's solution pack) methods. METHODS: Between February, 1990 and March, 1992, 142 patients underwent cold-knife conization were randomly allocated into 2 groups. The hemostasis was done by suture in one group and by Monsel's solution pack without suture in the other group. The patients' and cone specimens' characteristics as well as short-term outcome were recorded and compared using Chi-square test, Fisher exact test and t-test where appropriate. RESULTS: The patients' characteristics, cone size, and histologic diagnosis of both groups were comparable. The non-suture group had shorter operative time (10.69 +/- 7.86 vs. 20.04 +/- 6.99 minutes) and lesser late hemorrhage (2.9 vs. 15.9%) than the suture group (p < 0.05). There was no statistical difference in the operative blood loss. CONCLUSION: The non-suture method of conization should replace the traditional suture method.

Combined radiotherapy and hysterectomy in the treatment of high risk stage II invasive carcinoma of the uterine cervix.

This is a prospective non-randomized study of 127 patients with stage IIB carcinoma of the cervix treated with irradiation and followed by surgery at Ramathibodi Hospital between 1980 and 1989. The criteria for combined treatment were an enlarged cervical mass of over 5 cm, including a barrel-shaped cervix, inadequate or improper radium insertion due to obliterated cervical os, and endometrial extension. The 5-year survival rate was 84.37%. The incidence of pelvic failure was 10.2% and extrapelvic failure was 6.3%. Those revealing residual disease in hysterectomy specimens had a worse prognosis. The increase in the survival rate in this study as compared to other reports may have been due to the use of higher dosages of irradiation. It is concluded that combined treatment was effective in dealing with poor prognosis groups of carcinoma of the cervix. It improved the pelvic and extrapelvic control as well as the survival rate with acceptable complications.

Prognostic factors associated with recurrence in stage IB cervical carcinoma after radical hysterectomy and pelvic lymphadenectomy.

Radical hysterectomy with pelvic lymphadenectomy is the treatment of choice for stage IB cervical carcinoma. Recurrence of disease usually results in poor prognosis. The prognostic factors associated with recurrence were analyzed in 182 patients with stage IB cervical carcinoma treated with radical hysterectomy with pelvic lymphadenectomy at Department of Obstetrics and Gynaecology, Ramathibodi Hospital from May 1969 to December 1988. Twenty-one patients (11.5%) developed recurrent cervical cancer. Factors which were found to have statistical significance associated with recurrence were positive lymph node, positive surgical margin and cervical lesion size of 3 cm or more. The application of these factors was discussed.

Uterine sarcomas at Ramathibodi Hospital (1969-1986).

Uterine sarcoma is a rare gynecological malignancy. This retrospective study covered a period of 18 years and during that time 15 cases of uterine sarcoma were treated in Ramathibodi Hospital. It represented an incidence of 6 per 10,000 gynecological admissions. There were 9 leiomyosarcomas, 3 endometrial stromal sarcomas, 2 mixed mullerian sarcomas, and one rhabdomyosarcoma. The average age of the patients was 45.67 years, 3 under 40 and five after menopause. The mean parity was 4. The most common presenting symptoms were vaginal bleeding and abdominal mass. The diagnostic curettage was positive in only 2 out of 7 cases. All were treated by hysterectomy and bilateral salpingo-oophorectomy. Two out of 4 cases who received adjuvant radiotherapy or chemotherapy were still-alive at 1 and 3 year follow-up. The crude survival rate was 40 per cent.

Assessment of endocervical curettage in colposcopy.

Colposcopy has become an accepted diagnostic procedure in the management of patients with abnormal cervical cytology. To assess the value of the endocervical curettage in colposcopy, a retrospective review of 125 cases who had the procedure done during the 20-month period (January 1986-August 1988) was carried out. The ECC were positive in 3 out of 57 (5.3%) patients with satisfactory examination and 24 out of 68 (35.3%) patients with unsatisfactory examination. In all 27 cases, there was insufficient tissue to make a diagnosis of invasive carcinoma. Of the 125 patients studied seventy-two (29 in the satisfactory group and 43 in the unsatisfactory group) underwent conization and/or hysterectomy. Endocervical curettage did not eliminate the need for cone biopsy in all cases of unsatisfactory colposcopy. The tissue diagnosis on ECC did not increase the diagnostic accuracy derived from the colposcopic directed biopsies in either group. There were 20 cases of invasive carcinoma (13 MIC, 7 invasive) in this study, the ECC were positive in 9. We concluded that the ECC has limited value in colposcopy.

The risk factors in the development of persistent trophoblastic disease following hydatidiform mole.

Hydatidiform mole (HM) is not uncommon in our country. Its dangerous sequalae is the fatal persistent trophoblastic disease (PTD). The prognostic risk factors for the development of PTD were analyzed in 108 cases of HM treated in Ramathibodi Hospital from 1978 to 1986. Statistical univariate analysis was by calculation of relative risk (RR) and chi-square test. The incidence of PTD was 27.8 per cent. The significant risk factors were the presence of theca-lutein cyst, gestational age of less than 16 weeks, "large for date" uterus, and patients' age of 40 years or more. Their RR were 4.25, 3.11, 3.00 and 2.68 respectively. These findings were comparable with previous reports. The use of prophylactic chemotherapy in patients with these risk factors was suggested.
