Survival after multimodality treatment for stage IIIC endometrial cancer

OBJECTIVE: Our purpose was to review our results of multimodality treatment of lymph node metastasis in endometrial cancer (stage IIIC). STUDY DESIGN: All patients underwent surgical staging for endometrial cancer with complete pelvic and aortic lymphadenectomy. All macroscopic nodal metastases were resected. Patients with microscopic nodal metastasis received adjuvant teletherapy, whereas those with macroscopic nodal metastasis received chemotherapy (carboplatin AUC 5 and paclitaxel 135 mg/m2 every 3 weeks for 6 courses) followed by teletherapy. RESULTS: Twenty-one patients had stage IIIC disease, and one had stage IVB (inguinal nodal metastasis). Sixty-four percent of tumors were poorly differentiated. Fifty-five percent of patients had pelvic nodal metastasis only and 41% had macroscopic nodal metastasis. At a median follow-up of 3.8 years, 32% of patients had recurrence, all extrapelvic. Overall mean survival was 48 months and progression-free survival was 40 months. Overall survival for microscopic nodal metastasis was >60 months versus 35 months for macroscopic metastasis. Overall survival for pelvic nodal metastasis was 53 months versus 42 months for aorticinguinal metastasis. There were no complications from lymphadenectomy, a 22% chemotherapeutic toxicity, and a 14% radiation toxicity. CONCLUSION: Our surgical, chemotherapeutic, and radiation treatment protocol for stage IIIC endometrial cancer produced minimal toxicity and good survival.     

Para-aortic lymphadenectomy for primary fallopian tube cancer

Objective

To investigate the topography of lymph node spread and the need for para-aortic lymphadenectomy in primary fallopian tube cancer (PFTC).

Methods

Twenty-six women were diagnosed with PFTC at Cheil General Hospital and Women's Healthcare Center, Seoul, Korea, between March 1992 and November 2009. Of the 26 patients, we retrospectively analyzed 15 patients who underwent complete staging surgery, including bilateral pelvic and para-aortic lymphadenectomy.

Results

The median follow-up period was 57.9 months (range, 3-185 months) and the 5-year survival rate was 86.3%. Five (33.3%) patients were diagnosed with FIGO stage I, 1 (6.7%) with stage II, and 9 (60%) with stage III cancer. The median number of lymph nodes removed was 53.8 (range, 18-106 nodes). Four (26.7%) patients had nodal involvement: 2 patients with para-aortic lymph node involvement and 2 patients with both pelvic and para-aortic lymph node involvement. None of the patients was positive for pelvic lymph nodes alone.

Conclusion

A comprehensive para-aortic lymphadenectomy was necessary for accurate staging in PFTC.     

Impact of Surgical Staging in Women with Locally Advanced Cervical Cancer

OBJECTIVE: The aim of this study was to evaluate the impact of surgical staging in the treatment and outcome of women with locally advanced cervical cancer. METHODS: Ninety-eight women with locally advanced cervical cancer treated between 1993 and 1997 were retrospectively reviewed. Survival probabilities were calculated by the Kaplan-Meier product limit method and compared with the log-rank test. RESULTS: Of the 98 women treated over the 5-year period, 86 were surgically staged: 61 by a retroperitoneal approach, 18 by laparoscopy, and 7 by laparotomy. Median blood loss was 120 cc and median length of hospitalization was 3 days. Preoperative CT scans (n = 55), when compared with surgical findings, missed macroscopic nodal disease in 20% and microscopic disease in 15% and overcalled disease in 10% of cases. Lymph node metastases were found in 45/86 patients (52%): 12 microscopic and 33 macroscopic. The highest level of nodes found to be involved was pelvic in 23, common iliac nodes in 3, para-aortic nodes in 14, and scalene nodes in 5 cases. Of the 86 patients, 49 received pelvic radiation, 27 received extended field radiation, and 10 were identified for palliative treatment only (5 scalene node metastasis, 5 extensive intraperitoneal disease). For node-negative patients, 5-year survival was 74%; for microscopic nodal involvement it was 58%; and for macroscopic involvement it was 39% (P = 0.007). Five-year survival for women with para-aortic node involvement was 52%. Number of nodes involved was a significant prognostic variable (P = 0.008). Patients who received chemotherapy had a 5-year survival of 68% compared to 35% for those who did not (P = 0.06). Factors which did not affect survival included age, histology, type of surgery, stage, and type of radiation (pelvic vs extended). CONCLUSION: Surgical staging of women with locally advanced cervical cancer can be performed with acceptable morbidity and it provided more accurate information than CT scans and resulted in a modification of the standard pelvic radiation field for 43% of our patients. The information obtained from surgical staging allows better individualization of therapy, which may improve overall clinical outcome.     

Para-aortic node biopsy in cervical and endometrial cancers: does it affect survival?

Two hundred ten patients with endometrial and cervical carcinoma had para-aortic node biopsies. Nineteen of the 210 patients (9.0%) had positive para-aortic nodes. These 19 patients received pelvic irradiation, and 18 patients received para-aortic irradiation. The incidence of para-aortic nodal involvement in cervical carcinoma was directly related to the stage of the disease. Eleven of the 12 patients with cervical carcinoma and positive para-aortic nodes received both pelvic and para-aortic irradiation. Three of these patients are alive without disease, resulting in a survival rate of 25%. These patients are surviving for 16, 30, and 41 months. The incidence of positive para-aortic nodes in endometrial adenocarcinoma was related to the uterine length and the histologic grade. The survival rate for patients with endometrial adenocarcinoma and positive para-aortic nodes in this study was 57.1%. Four patients have survived for 1, 30, 60, and 71 months. There were no surgical deaths or radiation therapy complications directly attributable to para-aortic biopsy or irradiation.     

Long-term survival after concomitant chemoradiotherapy prior to surgery in advanced cervical carcinoma

OBJECTIVE: To report the long-term survival of 35 patients who underwent surgery after concomitant chemoradiation for locally advanced cervical cancers. METHODS: From 1988 to 1992, 20 bulky IB-IIB patients and 15 stage III-IVA patients underwent surgery after concurrent chemotherapy (CDDP and 5-FU) and radiotherapy. 26 had a hysterectomy, 8 had an exenteration, 1 had no tumor resection. 21 had a para-aortic lymphadenectomy. Endpoints were recurrence and distant metastasis rates, overall survival (OS) and disease-free survival (DFS) at 5 and 10 years. Analysis included FIGO stage, type of surgery (palliative or curative), response to chemoradiation or para-aortic lymphatic status. RESULTS: Surgery had been only palliative in 6 cases (17.1%). A pelvic control has been achieved in 31 patients (88.6%). Pelvic recurrences occurred after a median interval of 7 months. Distant metastases occurred in 10 patients (28.6%), after a median interval of 20 months. So far, 16 patients have died (45.7%). The 10-year DFS is 56.7% in the whole series. Only the type of surgery significantly affected the OS. Only the para-aortic lymphatic status significantly affected the DFS. CONCLUSION: Associating chemoradiation with curative surgery, we obtained a 10-year DFS of 66.4% (OS 57.7%). Adjuvant surgery may increase the survival as it reduces the risk of local relapse.     

Para-aortic node sampling in small (3-cm or less) stage IB invasive cervical cancer.

Only 2 of 125 patients with FIGO stage IB invasive squamous or adenocarcinoma of the cervix 3 cm or less in diameter who underwent exploration for radical hysterectomy, bilateral pelvic lymphadenectomy, and para-aortic node sampling had metastases to the para-aortic nodes. No patient had gross para-aortic nodal involvement, and both patients with microscopic para-aortic nodal metastases had grossly positive pelvic nodal involvement. Para-aortic node sampling in patients with small stage IB cervical cancers undergoing radical hysterectomy may be restricted to patients with suspicious pelvic or para-aortic nodes.     

Resection of bulky positive lymph nodes in patients with cervical carcinoma

From January 1987 to April 1992, 34 patients had resection of bulky positive lymph nodes, detected either at the time of radical hysterectomy ( n = 23) or by computed tomographic (CT) scan of the pelvis and abdomen prior to radiation therapy for more advanced cervical cancer ( n = 11). Following nodal resection, 33 patients received pelvic external beam radiation, 28 received pelvic and para-aortic radiation, and 23 received four cycles of cisplatin chemotherapy. The median number of resected positive nodes was 4, with a range of 1–44. All macroscopic nodal metastases could be resected in each patient and morbidity was acceptably low. Positive nodes were confined to the pelvis in 17 patients, involved the common iliac group in nine patients, and involved the para-aortic area in eight patients. With a mean follow-up of 36 months, 23 patients (67.6%) were alive, of whom 20 were free of disease. For patients having a radical hysterectomy, actuarial 5-year survival was 80% for patients with disease involving pelvic and common iliac lymph nodes, and 48% for those with positive para-aortic nodes. Survival for patients with completely resected bulky pelvic and common iliac nodes was comparable to that for patients with micrometastases. This study suggests that every effort should be made to identify patients with cervical cancer who have bulky positive lymph node metastases, and to remove these nodes surgically prior to radiation therapy.     

FIGO stage IIIC endometrial carcinoma with metastases confined to pelvic lymph nodes: analysis of treatment outcomes, prognostic variables, and failure patterns following adjuvant radiation therapy.

OBJECTIVES: This study was undertaken to evaluate the prognostic significance of isolated positive pelvic lymph nodes on survival and to analyze other prognostic variables, overall survival, and failure patterns in surgically staged endometrial carcinoma patients with positive pelvic lymph nodes and negative para-aortic lymph nodes following radiation therapy (RT). METHODS: Between January 1, 1987, and December 31, 1997, 782 women underwent primary treatment for uterine cancer at Indiana University Medical Center. Through a review of the medical records, we identified 58 patients with pathologic stage IIIA, 27 patients with pathologic stage IIIB, and 77 patients with pathologic stage IIIC endometrial carcinoma. Patients with pathologically positive or unsampled para-aortic lymph nodes and patients who received preoperative radiation therapy were excluded, leaving a study group of 17 patients with nodal metastases confined to pelvic lymph nodes. Thirteen patients received adjuvant pelvic RT using AP-PA or four-field technique. A median dose of 5040 cGy was delivered. Four patients received whole abdominal irradiation (WAI) delivering a median dose of 3000 cGy. Two patients received vaginal cuff boosts of 1000 and 3560 cGy to 0.5 cm from the vaginal surface mucosa via Cs-137 brachytherapy. Two patients also received adjuvant chemotherapy (cis-platinum and doxorubicin) and/or hormonal therapy (megestrol acetate). Disease-free and overall survivals were estimated using the Kaplan-Meier method of statistical analysis and prognostic variables were analyzed using the log-rank test. RESULTS: With a median follow-up of 51 months the actuarial 5-year disease-free survival was 81% and the actuarial 2-year and 5-year overall survival rates were 81 and 72%, respectively. Univariate analysis revealed that positive peritoneal cytology in conjunction with positive pelvic lymph nodes imparts a greater risk of recurrence and decreased overall survival. There were no pelvic and/or upper abdominal failures, but there were recurrences in the para-aortic lymph nodes (two patients) and distantly (two patients). CONCLUSION: Surgery followed by postoperative pelvic RT is a viable treatment option for pathologically staged stage IIIC endometrial carcinoma with disease confined to the pelvic lymph nodes. Failures in the para-aortic region suggest a possible role for extended-field RT. Patients with positive peritoneal cytology in conjunction with nodal metastasis fared poorly with pelvic RT. Studies evaluating the efficacy of WAI are ongoing. Finally, substages within FIGO stage IIIC are recommended in an effort to better understand and define treatment strategies which might be appropriate for these patients.     

Biweekly gemcitabine and cisplatin in platinum-resistant/refractory, paclitaxel-pretreated, ovarian and peritoneal carcinoma

OBJECTIVES: Synergism between gemcitabine and cisplatin is supported by preclinical and clinical data. The present study explores the efficacy of a biweekly regimen in platinum-resistant/refractory, paclitaxel-pretreated ovarian and peritoneal cancer. METHODS: 50 paclitaxel-pretreated patients with platinum-resistant/refractory ovarian or peritoneal carcinoma who had previously received paclitaxel chemotherapy, were treated with six cycles of gemcitabine 1000 mg/m(2) followed by cisplatin 40 mg/m(2) on days 1 and 15, repeated every 4 weeks. RESULTS: The median platinum-free interval (PFI) was 4 months while the median number of previous treatment lines was 2. Chemotherapy was well tolerated. Objective responses were observed in 31.5% of evaluable patients (n=35). CA125 response was observed in 68% of patients with elevated CA125 (n=41). Median overall survival (OS) was 13.2 months (95% Confidence Interval, CI: 10.2-16.2) while progression-free survival (PFS) was 4.9 months (95%CI: 3.5-6.4). A PFI of less than 3 months was associated with lower objective response rates (15.8% versus 50%, p=0.03). CONCLUSIONS: Biweekly gemcitabine and cisplatin is feasible for patients with platinum-resistant ovarian or peritoneal cancer and is associated with a favorable toxicity profile. In a population with recent exposure to platinum, a PFI of less than 3 months was the major factor influencing response to chemotherapy.     

A phase I-II trial of intraperitoneal cisplatin and alpha-interferon in patients with persistent epithelial ovarian cancer

A toxicity, dose, and schedule study of intraperitoneal (ip) cisplatin and alpha-interferon was conducted as a salvage therapy for patients with persistent, advanced epithelial ovarian cancer after primary systemic therapy with cisplatin-combination chemotherapy. Twenty-four patients were entered into this prospective, nonrandomized phase I-II trial conducted at two institutions following a uniform protocol. Cisplatin doses were escalated from 45 to 90 mg/m2, and alpha-interferon doses were escalated from 10 to 50 x 10(6) IU. At protocol entry, 4 (16%) patients had microscopic residual disease at second-look laparotomy, 5 (21%) had minimal residual disease less than 5 mm, 7 (30%) had residual disease 5-20 mm, and 8 (33%) had bulky residual disease greater than 20 mm. Toxicity was acceptable overall. Hematopoietic toxicity included a grade 3 total white cell count in 12% of courses when the cisplatin dose was equal to or greater than 60 mg/m2. Renal toxicity was modest with grade 2 toxicity in 20% of courses with a cisplatin dose greater than 60 mg/m2. Gastrointestinal toxicity, especially nausea and vomiting was seen in most courses; however, it was grade 3 and dose-limiting in greater than 30% of courses with cisplatin 75-90 mg/m2. General malaise, fever, flu-like symptoms, chills, and myalgias were seen in most courses, but it was dose-limiting (grade 3) toxicity in 6-11% of cycles when the dose of interferon was 25-50 x 10(6) IU. There was no grade 4 toxicity. Thus, the maximum tolerated dose (MTD) of the combination is 60 mg/m2 cisplatin and 25 x 10(6) IU interferon. Eighteen patients were evaluable for response, 15 of whom had responded to prior cisplatin therapy and 3 had not. Of the 10 patients evaluable for clinical response, one patient (10%) achieved a complete response (CCR), and one (10%) had a partial response (PCR). The progression free interval (PFI) and survival were 11 months and 19 months, respectively, for the CCR patient, 6 and 11 months, respectively, for the PCR patient, and the mean survival for nonresponders was 8 months. The other 8 patients underwent a reassessment laparotomy: 2 (25%) achieved a complete pathologic response (CPR), and 3 (38%) had a partial pathologic response (PPR). Both pathologic responses were in patients with minimal residual disease less than 5 mm.(ABSTRACT TRUNCATED AT 400 WORDS)     

The use of paclitaxel and platinum-based chemotherapy in uterine papillary serous carcinoma.

OBJECTIVE: Uterine papillary serous carcinoma (UPSC) is an aggressive malignancy with a histologic appearance and pattern of spread that resembles that of papillary serous adenocarcinoma of the ovary. The current standard therapy for advanced ovarian cancer, cisplatin or carboplatin plus paclitaxel, results in high objective response rates for that tumor. This regimen has thus far not been evaluated in UPSC. METHODS: Twenty-four patients with UPSC treated with platinum-based chemotherapy and paclitaxel were retrospectively evaluated. Eighteen patients received these agents in the adjuvant setting (n = 9) or for disease persistent after initial surgical management (n = 9). Eleven patients received one or more courses of this drug combination for recurrent disease, 5 of whom had prior exposure in the initial setting. RESULTS: Mean follow-up was 35 months (range 6-72+). A median progression-free interval (PFI) of 30 months (range 8-61+) was seen in patients treated in the adjuvant setting. Objective response, indicated by normalization of an elevated prechemotherapy CA125 level, was seen in 8 of 9 patients treated for residual disease after initial surgery (median PFI of 13 months, range 5-38+). Objective response of both measurable and/or evaluable disease was seen in 7 of 11 patients treated for recurrent disease (median PFI of 9 months, range 4-18). Six patients had retreatment with one or both agents and 4 responded a second time. Overall, the regimen was well tolerated. CONCLUSION: Paclitaxel and platinum-based chemotherapy has demonstrated activity in UPSC with acceptable toxicity. These results merit further investigation of the possible role of these agents in patients with this aggressive histologic subtype.     

Extended-field radiotherapy and high-dose-rate brachytherapy with concurrent and adjuvant cisplatin-based chemotherapy for locally advanced cervical cancer: a phase I/II study

OBJECTIVE: The purpose of this prospective study was to investigate the toxicity and efficacy of integrating extended-field para-aortic and pelvic external radiation, high-dose-rate intracavity brachytherapy, and concurrent and adjuvant cisplatin-based chemotherapy for locally advanced cervical cancer. METHOD: A phase I/II study was performed from 1998 to 2003 including sixty-three patients with both clinical FIGO and MRI/CT-based TNM stage IIB-IVA cervical cancer. Patients were treated with extended-field external radiation to the para-aortic and pelvic regions with 45 Gy in 25 fractions, and an additional boost to the gross nodes to 50.4 Gy and the parametrium to 59.4 Gy. Patients also received a high-dose-rate (HDR) intracavity brachytherapy with doses of 22-31 Gy to point A in 4-6 fractions. Concurrently, two cycles of cisplatin (50-80 mg/m(2)) were administered in weeks 1 and 5 during radiotherapy, as well as two cycles of cisplatin (60-80 mg/m(2)) for 1 day and 5-fluorouracil (600-800 mg/m(2)) for 4 days at 1 and 2 months after completion of radiotherapy. The treatment-related acute and late side effects were evaluated using RTOG criteria, and the disease control and survival rate were calculated using the Kaplan-Meier method. The median follow-up interval was 36 months. RESULTS: All sixty-three patients completed the planned extended-field radiotherapy and high-dose-rate brachytherapy with 2 concurrent cycles of cisplatin. Fifty-eight (92%) patients received 2 cycles of the post-radiation adjuvant chemotherapy of cisplatin and 5-fluorouracil. RTOG grade III acute toxicity was gastrointestinal (2%) and hematological (10%). No patient had grade IV acute toxicity. Late grades III-IV morbidity actuarial risk of 6% at 6.5 years primarily involved the injuries to the bowels requiring surgical intervention for intestinal obstruction or fistula formation. Initial sites of recurrence were locoregional failure alone (pelvic and para-aortic regions within the radiation field), 3%; distant metastases only, 8%; and locoregional failure plus distant metastases, 8%. The observed rates at 3-year and 5-year of locoregional control, freedom from distant metastasis, and overall survival were 86% and 86%, 81% and 81%, and 81% and 77%, respectively. CONCLUSION: Incorporating HDR brachytherapy into a regimen including concurrent chemotherapy and extended radiation appears safe and effective.     

Intraperitoneal cisplatin chemotherapy in ovarian carcinoma patients who are clinically in complete remission.

Three courses of intraperitoneal cisplatin chemotherapy with systemic thiosulfate protection were administered to 31 stage II-IV ovarian carcinoma patients who were clinically in complete remission after completion of postoperative cisplatin-based combination chemotherapy. The 5-year survival rate was 60.4% and the median progression-free interval 35 months. Among 25 patients who underwent second-look laparotomy, the survival and the duration of the progression-free interval were significantly better in those with a pathologically confirmed complete response. Short-term intraperitoneal cisplatin chemotherapy should be considered for consolidation of treatment in ovarian carcinoma patients who are clinically in complete remission.     

Long-term results of concurrent radiation and chemotherapy for carcinoma of the cervix recurrent after surgery

Between 1981 and 1991, 41 patients with carcinoma of the cervix recurrent only in the pelvis, or pelvis and para-aortic nodes after initial surgery, were treated with concurrent chemo-radiation (CT-RT). The total dose of radiation was tailored to the disease extent. Radiation was delivered to the pelvis and/or pelvis plus para-aortic nodes. Concurrent infusional 5-fluorouracil 1.5 g m-2 day-1 was delivered with bid radiation for one to three courses of 3 or 4 days. In addition, 10 patients received one or two courses of intravenous mitomycin C (Mit C) 6 mg m⁻². Twenty-three of 40 evaluable (58%) had a complete response to CT-RT. Five have subsequently relapsed, two in pelvis alone, one in pelvis and distant sites and two with distant metastases only. Eighteen of 40 (45%) remain alive without disease from 3 to 113 months (median 57 months) after CT-RT. Sustained complete remissions and apparent cure have occured even in poor pronosis patients with pelvic side wall or common iliac nodal diease and those recurrent at short intervals from surgery. Using logistic regression the following varibles were examined for their prognostic significance for pelvic control and survival: Mit C, extent of pelvic diseases number of course of 5-FU, nodal status at original surgery and radiation dose. On multivariate analysis only the number of courses of 5-FU used was predictive of pelvic control and survival. Concurrent 5-FU and radiation is recommended as salvage therapy for patients wth recurrent locoregional cervical cancer.     

The impact of pre-therapy extraperitoneal surgical staging on the evaluation and treatment of patients with locally advanced cervical cancer.

OBJECTIVE: The use of extraperitoneal surgical staging prior to treatment in patients with bulky or locally advanced cervical cancer allows the detection and treatment of disease beyond the standard pelvic radiation fields. This study was conducted to evaluate the impact of extraperitoneal surgical staging in the treatment and outcome of patients with locally advanced cervical cancer. METHODS: 51 patients with locally advanced cervical cancer treated between 1985 and 1998 were retrospectively reviewed. Information on morbidity, usefulness, and results of surgery and patterns of disease recurrence were obtained. Survival distributions were calculated by the Kaplan-Meier product limit method and compared with the log-rank test. RESULTS: All 51 women were surgically staged by an extra-peritoneal approach. Preoperative CT scans (n=27) when compared with surgical findings showed sensitivity for pelvic and para-aortic lymph node metastasis of 39%, specificity of 88%, positive predictive value of 39% and negative predictive value of 88%. Lymph node metastases were found in 30/51 patients (59%). There were no significant treatment delays or surgical morbidity as a result of extra-peritoneal surgical staging. In 21 patients (41%), the highest level of involved nodes was in the pelvis and they were treated with pelvic radiation. The para-aortic nodes were involved in nine patients (18%) and were treated with extended field radiation. All patients also received concurrent radiosensitization with chemotherapy. The estimated survival for the entire group was 60% at 5 years. For node negative patients, estimated 5-year survival was 67% while it was 54% for all node positive patients (p=0.17). Analysis according to anatomic site of involved nodes showed that the estimated 2-year and 5-year survival for those with pelvic nodal involvement was 81% and 64%, respectively. However, in the group of nine patients with para-aortic nodal disease, the estimated 2-year survival was 44%. Five (56%) were dead of disease with a median time to death of 16.0 months and four patients (44%) were alive with a median duration of follow up of 16.1 months. There was a statistically significant difference in survival for the group of patients with positive pelvic nodes only compared to the group with positive para-aortic nodes (p=0.03). The estimated 5-year survival by FIGO stage was 80%, 70% and 51% for stages Ib, II, III, disease, respectively. Factors that did not significantly affect survival included age, histology and type of chemotherapy. CONCLUSIONS: Pre-therapy extra-peritoneal surgical staging resulted in treatment modification in 18% of patients with locally advanced cervical cancer. The morbidity from surgery and subsequent radiation therapy was acceptable. The procedure is recommended to allow for individualization of treatment in patients with local-regional cervical cancer.     

Carcinosarcoma of the ovary-a case series

OBJECTIVE: To evaluate our experience with ovarian carcinosarcoma and identify prognostic factors. METHODS: Thirty-one cases of ovarian carcinosarcoma were identified over a 6-year time period through tumor registry and pathology records. Fisher exact test and log rank using Kaplan-Meier method (P < 0.05) were used to compare variables with outcome. RESULTS: All 31 patients underwent initial surgical treatment with an appropriate staging procedure. Stage distribution: 1 stage I, 6 stage II, 23 stage III, and 1 stage IV. The median follow-up was 28 months. The median survival for the entire group was 21 months. Early vs. advanced stage significantly influenced progression-free interval, P = 0.05. Nineteen patients were found to have stage IIIC disease and required debulking procedures. In patients with stage IIIC disease, presence of residual disease was associated with decreased overall survival, P = 0.03. 29 patients received adjuvant chemotherapy with 11 patients receiving ifosfamide/cisplatin and 16 patients receiving carboplatin/taxol. Progression-free interval was improved with the use of ifosfamide/cisplatin vs. carboplatin/taxol. The median PFI was 12 months in the carbo/taxol group and has not been reached in the ifos/cisplatin group (P = 0.005). The overall survival was also significantly improved with the use of ifosfamide/cisplatin, P = 0.03. In advanced stage patients, overall survival was not significantly influenced by type of adjuvant chemotherapy administered, P = 0.13. CONCLUSIONS: Ovarian carcinosarcoma has a poor overall prognosis with median survival rates reported in the literature ranging from 7-10 months. Our series, although limited by a small number of patients, exhibits a more encouraging median survival of 21 months for the overall group. Aggressive debulking to eliminate residual disease and the use of ifosfamide/cisplatin chemotherapy seem to be factors in this improved outcome.     

A phase II trial of mitomycin, vincristine, bleomycin, and cisplatin (MOBP) as neoadjuvant therapy in high-risk cervical carcinoma

Twenty patients with locally advanced or metastatic cervical carcinoma were treated with mitomycin, vincristine, bleomycin, and cisplatin (MOBP), prior to radiotherapy (RT) of curative intent. Five patients had stage I disease, 2 stage II, 10 stage III, and 3 stage IV. All but one patient with stage I and II disease had nodal metastases. Patients received two courses of MOBP prior to and cisplatin q 3 weeks during RT. Response rates after completion of MOBP and prior to RT were as follows: 3/18 (16.6%) patients had a complete response (CR), 10/18 (55.5%) had a partial response (PR), 3/18 (16.6%) had improvement, and 2/18 (11.1%) had no response (NR). Five patients developed radiation complications. Of 7 patients with stage I and II disease, 6 (86%) currently have no evidence of disease (NED) (median 27 months). Of 13 patients with advanced disease, 3 (23%) are NED (median 17 months), 8 (61.5%) have expired, and 2 (15.4%) are alive with disease. MOBP is associated with significant response rates in the untreated patient but has not improved survival in patients with advanced disease. Patients with early disease and positive nodes may benefit from this regimen.     

Secondary cytoreductive surgery for isolated nodal recurrence in patients with epithelial ovarian cancer

OBJECTIVES: To evaluate the feasibility and associated survival outcome of secondary cytoreductive surgery in patients with isolated lymph node recurrence of epithelial ovarian cancer. METHODS: Twenty-five patients with epithelial ovarian cancer who underwent secondary cytoreductive surgery for isolated lymph node recurrence were identified from tumor registry databases. Demographic, diagnostic, operative, pathologic, and follow-up data were abstracted retrospectively. Overall survival was calculated using the Kaplan-Meier method. RESULTS: The median age at time of primary surgery for ovarian cancer was 55 years; 72% of patients had FIGO III/IV disease, and all had high-grade tumors. All patients received platinum-based chemotherapy following primary surgery. The median time from completion of primary chemotherapy to nodal recurrence surgery was 16 months (range=6 to 40 months). The distribution of nodal involvement was pelvic=12% (n=3), para-aortic=60% (n=15), inguinal=20% (n=5), peri-cardiac=4% (n=1), and pelvic plus para-aortic=4% (n=1). The maximal nodal tumor diameter ranged from 1.5 cm to 14 cm, with a median of 3.0 cm. Optimal secondary cytoreductive surgery (residual disease 相似文献   

Effectiveness of postoperative chemotherapy for para-aortic lymph node metastasis of endometrial cancer

OBJECTIVE: To examine the effectiveness of postoperative chemotherapy for para-aortic lymph node (PAN) metastasis in patients with endometrial cancer. METHODS: Among 350 clinical stage I-II endometrial cancer patients who underwent systemic pelvic and para-aortic lymphadenectomy during the period 1995 through 2002, 26 patients were identified with PAN metastasis. Of these patients, nine had only one positive PAN and 17 had two or more positive PANs (mean 4.9, range 1-22). All patients were treated postoperatively with a single chemotherapy regimen consisting of ifosfamide, epiadriamycin, and cisplatin scheduled for 5 cycles. Median (range) follow-up for surviving patients was 85 (38-119) months. Treatment outcome, including disease-free survival relative to the number of positive PANs, was investigated. RESULTS: Among the 26 patients with PAN involvement, four developed recurrence. Three of the four patients had 10 or more positive PANs. Estimated 5-year disease-free survival rates were 89% for patients with one positive PAN, 82% for those with two or more positive PANs, and 85% for all patients. No significant difference was identified between the first two groups (P = 0.6543). CONCLUSIONS: Postoperative chemotherapy can yield a favorable outcome in endometrial cancer patients with PAN metastasis, even those with multiple positive nodes.     

Endometrial carcinoma in women aged 40 years or younger: a Japanese experience

We report on the clinical and pathologic findings in 17 cases of endometrial carcinoma in Japanese women aged 40 years or younger. Age of the patients ranged from 16 to 40 years, with a median of 35 years. Nine of 17 tumors (52.9%) were stage I or II (FIGO 1988) but 8 (47.1%) were stage III. Four of the 8 patients with stage III disease had pelvic lymph node metastases and one also had para-aortic lymph node metastasis. One patient had metastasis to the ovary and peritoneal cytology was positive in 4 patients. Histologically, 13 of these 17 patients had endometrioid adenocarcinoma, 3 had adenoacanthoma and 1 had an undifferentiated carcinoma. Ten were well differentiated tumors (G1), 3 were moderately differentiated tumors (G2), and 4 were poorly differentiated tumors (G3). Nine of 17 (52.9%) showed deep myometrial invasion (more than a half of the myometrium) and 5 of 17 (29.4%) demonstrated lymphatic/vascular space invasion. Pelvic and para-aortic lymph node metastases were seen in 4 of 15 (26.7%) and 1 of 15 (6.7%), respectively. Two of these 17 patients died of disease in a relatively short follow-up period. In our experience there is no difference in the survival rates between patients aged 40 years or younger and those over 40 years.
