Stage IIIC endometrioid corpus cancer includes distinct subgroups

OBJECTIVE: Because stage IIIC corpus cancer is a heterogeneous substage, the outcomes of patients with stage IIIC disease were assessed according to the extent of extrauterine disease. METHODS: From 1984 through 1993, 51 patients with surgical stage IIIC corpus cancer were treated at our institution; 5 patients had tumors with nonendometrioid histologic features and were excluded from the analyses. Of the 46 patients with endometrioid carcinoma, 22 had lymph nodes as the only site of extrauterine disease (stage IIIC(0)) and 24 also had peritoneal cytologic, uterine serosal, adnexal, or vaginal involvement or a combination of these (stage IIIC(ab)). The mean number of lymph nodes removed was 18 pelvic and 8 aortic nodes. Median follow-up for surviving patients was 84 months. RESULTS: Patients with stage IIIC(0) cancer had a 5-year cause-specific survival (CSS) of 72% and a 5-year recurrence-free survival (RFS) of 68%, and those with stage IIIC(ab) had a CSS of 33% and an RFS of 25% (P < 0.01). Of the 22 patients with stage IIIC(0) endometrioid cancer, 21 had adjuvant radiotherapy (1 also received chemotherapy) and 1 was not treated. Relapse occurred in 7 (32%) patients, with only 1 having an initial failure component outside the node-bearing areas (lung). Of the 24 patients with stage IIIC(ab) cancer, 16 received adjuvant radiotherapy (1 had concomitant chemotherapy), 2 had chemotherapy, 4 had hormonal therapy, and 2 were not treated. We observed 16 recurrences (67%). Of the 14 patients with known initial sites of failure, 9 had an extranodal failure component. CONCLUSION: Assessment of CSS, RFS, and sites of relapse suggests that FIGO surgical stage IIIC endometrioid corpus cancer includes two distinct and readily separable subgroups: (1) stage IIIC(0), nodal involvement only, and (2) stage IIIC(ab), nodal plus cytologic, uterine serosal, adnexal, or vaginal involvement, or a combination of these. Our results also suggest that different treatment strategies are needed for these subgroups.     

Carcinoma of the cervix, FIGO Stage IB: treatment failures

All patients with carcinoma of the cervix, FIGO Stage IB, treated at the University of Minnesota Hospitals during a 10-year period were reviewed. Of the 220 patients 31 (14.0%) developed recurrent disease and did not survive. Thirteen patients had pelvic wall recurrences, with concurrent cervical involvement. No patient had a resectable pelvic recurrence. Hysterectomy was subsequently performed on 10 of the 172 patients who received radiation therapy. Carcinoma was not present in any of the operative specimens although two patients with adenocarcinoma later died of metastatic cancer. Median time of recurrence was 9 months, with median survival following recurrence of 6 months. Cervical cytology was not of value in the early diagnosis of recurrent disease. The 5-year adjusted actuarial survival rate for patients with adenosquamous carcinoma was significantly lower than that for patients with squamous cell carcinoma. The median age of patients not surviving with adenosquamous carcinoma was significantly lower than that for patients not surviving with squamous cell carcinoma. Patients with invasive carcinoma presumably confined to the cervix may have disseminated disease. It is essential such selected patients receive primary treatment that includes systemic therapy.     

Reoperation for palliation of recurrent malignant bowel obstruction in ovarian carcinoma

OBJECTIVE: While initial surgical treatment for palliation of malignant bowel obstruction is well described, data on reoperation for palliation of recurrent obstruction in ovarian carcinoma are limited. The purpose of this study was to analyze the outcome of patients undergoing reoperation for repeat bowel obstruction. METHODS: We reviewed the records of all patients with ovarian cancer who underwent repeat surgery for recurrent, malignant bowel obstruction at our institution between 1994 and 2002. RESULTS: Ten patients were identified. All patients had bowel obstruction caused by recurrent ovarian carcinoma and had a previous corrective surgical procedure for malignant bowel obstruction. The mean age at diagnosis of repeat obstruction was 54.1 years (range, 34-74 years). All patients had initial stage III or IV disease with moderately to poorly differentiated cancers. No patient received prior radiation therapy. The sites of obstruction in patients were as follows: small bowel, 3; large bowel, 3; both small and large bowel, 4. The mean number of prior laparotomies was 2.7 (range, 2-5). The mean interval from previous surgery for bowel obstruction to recurrent bowel obstruction was 8.3 months (range, 1-22 months). Surgical correction was possible in 5 (50%) of 10 patients, with 3 (60%) of these 5 patients obtaining successful palliation. Successful palliation is defined as the ability to tolerate a regular or low-residue diet at least 60 days postoperatively. Complications included enterocutaneous fistulas in three patients (two had enterotomies at time of surgery) and wound infection in one patient. There were no postoperative mortalities. The mean postoperative stay was 15.8 days (range, 8-29 days). Two of the three patients successfully palliated presented with a subsequent obstruction at 3 and 5 months postoperatively and were treated with gastrostomy tubes. The median length of survival for the entire cohort from the date of surgery for repeat obstruction was 4.5 months (range, 3-17 months). CONCLUSIONS: Patients undergoing repeat surgery for recurrent bowel obstruction have a low likelihood of successful palliation (30%). The surgery is associated with significant complications after surgery, rapid development of subsequent bowel obstructions, and limited survival rates. Alternative management approaches such as percutaneous endoscopic gastrostomy (PEG) tube placement should be considered in this group of patients.     

Long-term survival of 106 stage III ovarian cancer patients with minimal residual disease after second-look laparotomy and consolidation radiotherapy

OBJECTIVE: Attempts to increase survival in stage III ovarian cancer patients with minimal residual disease at second-look laparotomy have included consolidation radiotherapy. We present long-term survival of 106 consecutive patients treated between 1983 and 1993 in 4 French institutions for stage III ovarian adenocarcinoma with first-look debulking, cisplatin-based chemotherapy, second-look surgery with a residual disease <1 cm and consolidation radiotherapy. METHODS: Median age was 52 years. Residual disease after first look surgery was <1 cm for 40.5% of patients. Median number of chemotherapy cycles was 6 (range 4-12). Residual disease <1 cm at second-look laparotomy was observed in 79% of the patients, with 33% of patients in complete histologic remission. Residual disease <1 cm was obtained in all patients after tumor excision during second-look surgery. Radiation was performed using a linear accelerator with a whole abdomen dose of 22.5 Gy, an additional 22 Gy pelvic boost for 71 patients, and an additional 12 Gy lombo-aortic boost for 33 patients. RESULTS: Median follow-up was 14 years. Radiation was stopped for acute toxicity in 11 patients. Long-term toxicities included radiation enteritis in 21 patients with 9 patients requiring surgery for bowel obstruction. Four deaths were related to enteritis complications. Overall survival at 5 and 10 years was respectively 53% and 36%. CONCLUSION: This sequential treatment with final consolidation abdominopelvic radiotherapy is an effective treatment for a selected group of stage III ovarian cancer patients with a high intestinal toxicity incidence.     

Limited-Field Radiotherapy as Salvage Treatment of Localized Persistent or Recurrent Epithelial Ovarian Cancer

Thirty-five patients with persistent or recurrent epithelial ovarian cancer were treated with salvage pelvic or para-aortic radiotherapy for disease limited to the pelvis (29), para-aortic retroperitoneum (5), or vaginal cuff (1). Prior therapy included a median of 3 chemotherapeutic drugs (range, 1-7) over a median of 12 cycles (range, 5-39); 12 patients had received intraperitoneal chemotherapy. The median number of prior laparotomies was 3 (range, 2-5). Including pelvic boosts, the median dose delivered to the treatment field was 4600 cGy (range, 4000-7000); 2 patients received additional treatment with a permanent ¹²⁵I implant. All patients completed therapy, although 5 (14%) with grade 3 toxicity required a treatment break. Late bowel complications unrelated to recurrence occurred in 3 patients (9%). Median actuarial and progression-free survivals for all patients from start of radiotherapy were 40 and 14 months, respectively. At least 16 of 26 (62%) recurrences involved the treatment field. Multiple prognostic factors were evaluated in terms of recurrence, survival, and acute and chronic complications, but no significant prognosticators were detected. These findings indicate that limited-field salvage radiotherapy has an acceptable complication rate and may prolong the symptom-free survival interval in selected patients.     

Whole-abdominal radiotherapy for patients with minimal residual epithelial ovarian cancer

Sixteen patients with advanced epithelial ovarian cancer who were treated with cytoreductive surgery followed by multiagent chemotherapy were found to have residual tumor masses less than 2 cm in greatest diameter at reexploration and were treated with whole-abdominal radiation (19-31 Gy). Thirteen patients also received pelvic boosts to a total pelvic dose of 41-53.7 Gy. Radiotherapy was completed in all but 2 patients after treatment delays in 7 patients. Early treatment complications included myelosuppression in 11 patients, diarrhea in 3, and a self-limited small bowel obstruction in one. Delayed complications were severe and included 9 patients with radiation enterocolitis, 8 of whom required intestinal resection or diversion. One additional patient with radiation cystitis required instillation of formalin to control bleeding. Two patients are without evidence of disease 28 and 30 months following radiotherapy, while the remaining 14 patients have recurred after a median progression-free interval of 9 months (range 1-30 months). All patients who recurred failed within the treatment field and died of cancer after a median interval of 19 months following radiotherapy and 9 months after documentation of progression. These data suggest that few patients with persistent ovarian cancer following surgery and chemotherapy will be salvaged with radiotherapy.     

Chemotherapy and Total Parenteral Nutrition for Advanced Ovarian Cancer with Bowel Obstruction

We retrospectively reviewed the medical records of 21 patients with advanced epithelial ovarian carcinoma treated with intravenous chemotherapy in an attempt to restore intestinal function following small-bowel obstruction. All patients had a drainage gastrostomy tube placed for palliation of vomiting, and 11 patients received concomitant total parenteral nutrition (TPN). Eight (38%) patients were treated with single-agent paclitaxel, 7 (33%) received platinum-based regimens, and 6 (29%) received other second-line chemotherapy. The median survival for all patients post-gastrostomy tube placement was 84 days. The median survival for patients with recurrent ovarian cancer who received salvage chemotherapy and TPN was 89 days, longer than for patients who received salvage chemotherapy alone (71 days) (P= 0.031). Two of three patients with newly diagnosed ovarian cancer and concomitant bowel obstruction had sufficient temporary response from chemotherapy with resolution of obstruction and removal of the gastrostomy tube. Chemotherapy was ineffective in restoring bowel function in heavily pretreated patients with recurrent disease.     

Management of ovarian cancer in patients older than 80 years of Age

OBJECTIVE: The objective of this study was to examine the treatment, associated morbidity, and survival in very elderly patients with epithelial ovarian cancer. METHODS: A retrospective analysis of patients 80 years of age and older treated for epithelial ovarian cancer by the Gynecologic Oncology faculty at the University of California Irvine was performed. RESULTS: Eighteen patients were older than 80 years of age at the time of diagnosis of ovarian cancer. Median age was 83 years (range 80-86 years). There were 2 stage I, 10 stage IIIC, 4 stage VI, and 2 unstaged patients. One patient had a tumor of low malignant potential, 4 patients had grade II tumors, and 10 patients had tumors that were grade III. Eighty-three percent of patients had one or more preexisting medical illnesses. Cardiac disease, stroke, and hypertension were most common. Sixteen of 18 patients (88%) underwent primary debulking surgery. American Society of Anesthesiologists physical status classification was as follows: 7/16 (44%) class II, 6/16 (38%) class III, and 2/16 (13%) class IV. The procedures performed included 16 bilateral salpingo-oophorectomies, 11 total abdominal hysterectomies, 16 omentectomies, 3 lymph node dissections, and 7 bowel resections. Four (25%) patients were optimally cytoreduced to <1 cm of residual disease. Seventy-five percent of surgical patients received blood transfusions of 2 or more units PRBC. Mean EBL was 600 cc (range 200-4200 cc). Thirty-eight percent of patients experienced major postoperative morbidity. There were 7 patients with postoperative congestive heart failure, 3 with sepsis, 1 with aspiration pneumonia, and 2 postoperative deaths. Seventy-five percent of patients spent time in the intensive care unit. Median number of days was 3 (range 1-22 days). Mean postoperative stay was 8 days (range 6-57 days). Sixty-five percent of patients were discharged to home. The other patients were discharged to intermediate care facilities or nursing homes. Eighty-three percent of patients received chemotherapy. Of the 10 patients (63%) receiving adjuvant chemotherapy, the mean interval from surgery to initiation of therapy was 3 weeks (range 1-4 weeks). Overall median survival was 6 months (range 1-45 months). Median survival in patients with optimal debulking was 32.5 months (range 7-45 months) compared to 3.5 months (range 1-41 months) in patients suboptimally debulked. CONCLUSIONS: In patients older than 80 years of age who undergo debulking surgery for ovarian cancer, serious medical comorbidity and advanced ASA status are common. Despite aggressive surgical effort and frequent blood transfusions, optimal debulking to less than 1 cm is achieved in only 25% of patients. Impressive morbidity and mortality occurs in this group of patients, but most patients are discharged to home and are able to receive postoperative chemotherapy.     

Whole abdominal radiotherapy following second-look laparotomy for ovarian carcinoma.

AIM: The safety and efficacy of whole abdominal radiotherapy was evaluated as salvage or consolidation treatment for ovarian cancer patients treated with primary surgery and chemotherapy, followed by second-look laparotomy (SLL). Overall survival and acute and late toxicity of treated patients were assessed. METHODS: Patients were recruited between April 1981 and June 1994. All patients had SLL performed at Royal Prince Alfred Hospital after completion of primary chemotherapy. Data collected included demographic details, diagnosis, tumor stage, histology, grade, adjuvant chemotherapy, and radiotherapy. Radiation dose and fractionation, field size, boost volume and dose, failure to complete treatment and treatment interruptions, renal dose, and acute and late toxicity were recorded. RESULTS: Fifty-one patients were evaluated; the median age was 51 years. Median follow-up for patients still alive was 62 months. Prior to 1988, chemotherapy comprised oral chlorambucil, with or without cisplatin (n = 25), while after this date all patients (n = 26) received primary cisplatin-based therapy. A radiation dose of 22. 5 Gy over 22 fractions was planned to the whole abdomen followed by a pelvic boost of 22 Gy in 11 fractions. Radiotherapy was completed in 37 (73%) patients. Treatment interruptions were necessary in 12 (24%) patients. Thrombocytopenia, neutropenia, nausea, vomiting, and diarrhea were the main causes of incomplete or interrupted treatment. Late bowel toxicity was seen in 6 (12%) patients, 2 of whom required laparotomy to relieve obstruction. There were no treatment-related deaths. Seven of the 51 patients are alive and free of disease, 2 died from other causes, and 2 are alive with evidence of recurrent or progressive disease. Mean follow-up time for surviving patients is 78.5 months. Overall survival at 2, 5, and 10 years was 65, 27, and 10%, respectively. Residual disease after primary surgery, smaller preirradiation tumor residuum, and completion of radiotherapy were independently associated with improved overall survival. CONCLUSION: In this poor-prognosis group of patients, a combined approach of surgery, chemotherapy, and radiotherapy, while associated with acceptable toxicity, may not afford a prolongation of survival.     

Phase II trial of topotecan and cisplatin in persistent or recurrent squamous and nonsquamous carcinomas of the cervix

OBJECTIVE: Cisplatin is a standard treatment in advanced, recurrent cervical cancer. Because topotecan is an established treatment in gynecologic malignancies such as ovarian cancer and exhibits nonoverlapping toxicity with cisplatin, a phase II trial was conducted to evaluate the tolerability and antitumor activity of a cisplatin/topotecan doublet in persistent or recurrent cervical cancer patients. METHODS: Patients with bidimensionally measurable persistent or recurrent squamous cell and non squamous cell cervical cancer and adequate bone marrow were enrolled. Patients received 50 mg/m(2) of cisplatin intravenously over 1 h on Day 1 and 0.75 mg/m(2) of topotecan intravenously over 30 min on Days 1, 2, and 3 of 21-day cycles for six cycles or until disease progression. Tumor response and regimen toxicity were assessed using established Gynecologic Oncology Group criteria. RESULTS: Thirty-two of 35 enrolled patients were evaluable for toxicity and tumor response. All but 2 evaluable patients had received previous radiotherapy. No patient received prior chemotherapy. The cisplatin/topotecan doublet was well tolerated, with 77 and 78% of courses given without interruption or delay and at full doses, respectively. As anticipated, the most common toxicity was hematologic, with grade 3/4 neutropenia and thrombocytopenia reported in 30 and 10% of cycles, respectively. The overall response rate was 28% (9/32), with 3 complete and 6 partial responses. The antitumor response in nonirradiated fields (30%) was similar to the response observed in previously irradiated fields (33%), suggesting good drug penetration. Median duration of response was 5 months (range, 2 to 15+ months). An additional 9 (28%) patients achieved stable disease. Median survival was 10 months, with 3 patients in lasting remission. CONCLUSIONS: These results demonstrate that the cisplatin/topotecan combination is safe, well tolerated, and active in persistent or recurrent cervical cancer patients. A phase III, multicenter trial is under way (cisplatin/topotecan versus cisplatin) based on these favorable results to confirm the safety and efficacy profile in this patient population.     

Treatment of advanced or recurrent adenocarcinoma of the endometrium with doxorubicin and cyclophosphamide

Thirteen patients with recurrent or advanced endometrial carcinoma were treated with a combination of doxorubicin (40 mg/m2 IV) and cyclophosphamide (600 mg/m2 IV). All patients had been refractory to prior radiotherapy and hormone therapy. None of the patients had received prior chemotherapy. Six of the 13 patients (46%) achieved an objective response: 1 complete response (8%) and 5 partial responses (38%). Median overall survival was 10 months (range 3-20 months). Doxorubicin and cyclophosphamide is an active combination in patients with advanced endometrial cancer.     

Survival of nonsurgically staged patients with negative lymphangiograms who had Stage IIB carcinoma of the cervix treated by pelvic radiation plus hydroxyurea

Twenty patients with Stage IIB carcinoma of the cervix who did not undergo pretherapy para-aortic lymphadenectomy, but who had negative preradiation therapy lymphangiograms, were treated with pelvic radiation plus hydroxyurea. Patients received a median of 5020 rads of pelvic radiation plus 4000 rads of radium to point A. During radiation therapy and for a total of 12 weeks, patients received hydroxyurea administered at a dose of 80 mg/kg of body weight every 3 days if the white blood cell count was greater than or equal to 2,500/mm3 and platelets were greater than or equal to 75,000/mm3. The median follow-up time was 28 months (6 to 83 months). The estimated 5-year survival rate was 92%. Seventeen patients are alive with no evidence of disease (median, 28 months); one died of intercurrent disease with no evidence of disease (17 months); one is alive with no evidence of disease after recurrence (18 months); and one died of cervical cancer (22 months). The survival rate of patients with nonsurgically staged negative pretherapy lymphangiograms who had Stage IIB cervical cancer treated by pelvic radiation therapy plus hydroxyurea approximated the improved survival rate reported for patients with negative pretherapy para-aortic lymphadenectomy who were treated with pelvic radiation therapy plus hydroxyurea. Both studies would suggest that pelvic radiation plus hydroxyurea improves the rate of survival in patients with Stage IIB cervical cancer.     

Mesorectal lymph node involvement and prognostic implications at total pelvic exenteration for gynecologic malignancies

OBJECTIVES: To determine the incidence and prognostic implications of positive mesorectal lymph nodes in patients undergoing total pelvic exenteration for recurrent gynecologic malignancies. METHODS: We performed a retrospective chart review of all patients who had undergone total pelvic exenteration for a gynecologic malignancy between July 1992 and December 2003. Patient charts were reviewed for information regarding demographics, site of cancer, histology, pathology report, and time to recurrence. RESULTS: Fifty-eight women had undergone total pelvic exenteration for recurrent gynecologic malignancies during the study period and 57 were available for analysis. Primary cancer site was as follows: cervix, 37 (65%); vagina, 8 (14%); vulva, 5 (9%); and uterine corpus, 7 (12%). In 30 patients (53%), the mesorectal lymph node status was pathologically evaluated. Of these 30 patients, 3 (10%) had positive mesorectal lymph nodes at the time of total pelvic exenteration. All 3 patients had rectal wall involvement (rectal submucosa, 2; rectal mucosa, 1), and all 3 patients recurred within 4 months of pelvic exenteration. The median time to recurrence after surgery was 2.4 months in those patients with positive mesorectal lymph nodes compared with 7.3 months in those with negative mesorectal lymph nodes (P = 0.005). When individually adjusted for other prognostic variables, such as margin status, tumor grade, lymphovascular space involvement, primary cancer site, and histologic type, a finding of positive mesorectal lymph nodes was associated with a shorter time to recurrence of disease (all P < 0.05). CONCLUSIONS: Mesorectal lymph node involvement is a common finding at total pelvic exenteration, particularly in patients with rectal wall involvement. Patients with positive mesorectal lymph nodes appear to have a worse outcome with a shorter time to recurrence of disease.     

Chemotherapy with mitomycin c, ifosfamide, and cisplatin for recurrent or persistent cervical cancer

The efficacy and toxicity of mitomycin C (MMC), ifosfamide, and cisplatin in cervical cancer were evaluated. Between January 1997 and August 2003, 46 patients with locally recurrent, persistent, or disseminated cervical cancer were treated with MMC 6 mg/m(2), ifosfamide 3 g/m(2), and cisplatin 50 mg/m(2) (MIC regimen) repeated every 3 weeks (maximum six cycles). In eight patients (17%), the tumor involved the pelvis alone, in 11 (24%) the pelvis and extrapelvic sites, and 27 (59%) had only distant lesions. A total of 213 MIC cycles were administered (median six cycles per patient). Of the 44 evaluable patients, the overall response rate was 34% (9% complete and 25% partial responses). Median progression-free interval was 6 months (95% confidence interval [CI], 4-7 months), and overall survival was 10 months (95% CI, 6-14 months). Objective response was obtained in two patients (11%) with pelvic relapse within previously irradiated area and in 13 (50%) of those with extrapelvic lesions (P= 0.01). Leukopenia was seen in 59% of patients (grade 3 in 9%). Nonhematologic side effects were mild and relatively infrequent. In conclusion, MIC regimen provides satisfactory efficacy with acceptable toxicity in advanced cervical cancer patients. Better response is seen in lesions outside of the previously irradiated area.     

复发性卵巢癌合并肠梗阻行姑息性手术的临床分析

目的分析复发性卵巢癌患者合并肠梗阻行姑息性手术治疗的临床应用。方法回顾分析1997-2002年采用姑息性手术治疗(手术治疗)的67例复发性卵巢癌合并肠梗阻患者,并与同期未行手术治疗(非手术治疗)的75例复发性卵巢癌合并肠梗阻患者进行比较。采用COX回归分析法,分析行手术治疗患者选择的参考指标。结果手术治疗的67例患者中,58例(86．6％)完成预期手术操作,43例症状获得成功缓解,缓解率64．2％(43／67),占所有肠梗阻患者的30．3％(43／142)。67例患者的中位数生存期为7．8个月,43例症状获得成功缓解患者的中位数生存期为12．6个月;非手术治疗患者的中位数生存期为3．7个月。67例患者的围手术期死亡率为6．0％(4／67),并发症发生率为22．4％(15／67)。单纯结肠发生梗阻和复发肿块位于盆腔,可作为采用手术治疗患者选择的参考指标。结论采用姑息性手术治疗复发性卵巢癌合并肠梗阻,可使约1／3的患者获得较好疗效;而选择恰当的患者,是手术治疗的关键。     

Relapse patterns in FIGO stage IB carcinoma of the cervix

Site of recurrence and survival data were reviewed for 96 patients with FIGO stage IB cervical carcinoma treated between July 1978 and December 1986 with radical surgery (N = 55), radiation therapy (N = 30), or combination therapy (N = 11). There were 21 patients (21.8%) who suffered recurrences. After radiation 10 of 30 (33.3%) patients recurred versus 11 of 55 (20%) after radical surgery alone. Recurrences were observed in 6 of 14 (42.8%) patients with positive nodes, 11 of 61 (18%) patients with negative nodes, and 4 of 21 (19%) patients with unknown nodal status. The first manifestation of recurrence was central in 3, locoregional in 9, and distant in 9. The median disease-free interval (DFI) was 11 months for surgical and 10.5 months for irradiated patients. The 2-year disease-free survival was 83.6% for surgical patients and 73.3% for irradiated patients. The risk of distant metastases was 3 of 55 (5.4%) following radical surgery and 6 of 30 (20%) after radiation (P = 0.04). The median time to pelvic recurrence was 10 months and that for distant recurrence was 20 months (P less than 0.05). The median time to pelvic relapse was 9.5 months for radical surgery patients and 10 months for irradiated patients. The median time to distant recurrence was 20 months for radical surgery patients and 16.5 months for irradiated patients. Median survival in those who died of disease after a recurrence confined to the pelvis was 15 months versus 8 months for those with a distant recurrence (P less than 0.05). Our data confirm that (1) site of relapse is influenced by primary therapeutic modality and (2) pelvic recurrence manifests before distant recurrence; however, median DFI for all recurrences as well as for the subsets of pelvic and distant relapses is independent of primary modality. We suggest that an understanding of the natural history of cervical cancer recurrence will allow optimal use of resources in the follow-up of patients to detect recurrence.     

Management of endometrial adenocarcinoma with cervical involvement

Seventy-seven patients with endometrial cancer with cervical involvement were treated at Memorial Sloan-Kettering Cancer Center from 1968 to 1982. Fractional curettage specimens showed that 25 patients (32%) had involvement of cervical stroma and 52 (68%) had only detached fragments of carcinoma present in endocervical curettings. Six patients treated for palliation only are excluded from analysis of treatment and survival. Our preferred treatment during the time interval studied consisted of preoperative whole pelvic radiotherapy followed by modified radical hysterectomy and bilateral salpingo-oophorectomy with post-operative intravaginal brachytherapy. This regimen was well tolerated by the 37 patients so treated. The remaining patients were treated with a variety of regimens, most commonly radiotherapy and simple hysterectomy (25 patients). With a mean follow-up among survivors of 97 months, disease-free survival is 72%. Mean time to relapse was 19 months, with 90% of relapses occurring within 40 months. Initial sites of relapse included abdomen, 9 (12.6%); lungs, 8 (11.3%); brain, 2 (2.8%); lateral pelvis, 2 (2.8%); and bone, 1 (1.4%). Clinicopathologic variables significantly related to risk of relapse included presence of extrauterine disease at surgery (P = 0.0001), extent of cervical involvement as determined prior to hysterectomy (P = 0.001), depth of myometrial invasion (P = 0.005), and papillary serous histology (P = 0.0002). Treatment of endometrial cancer with cervical involvement with combinations of radiotherapy and surgery is well tolerated and results in an excellent long-term disease-free survival and a low rate of pelvic relapse.     

Postoperative vaginal brachytherapy alone is the treatment of choice for grade 1–2, stage IC endometrial cancer

The aim was to determine outcome and toxicity in grade 1-2, FIGO stage IC endometrial cancer patients treated with external beam radiotherapy plus vaginal cuff brachytherapy or vaginal cuff brachytherapy alone. Between 1986 and 1999, a total of 132 patients were diagnosed with FIGO stage IC endometrial carcinoma. The median age was 67.5 years (range, 36-88). Median follow-up was 54 months (range, 6-157). Grade 1 disease was present in 64 patients, grade 2 in 45 patients, and grade 3 in 23 patients. Patients with grade 3 disease usually received external radiotherapy and were excluded from this analysis. Of the patients with grade 1-2 disease, 31 received brachytherapy alone and 78 received both external radiotherapy and brachytherapy. Ten (8%) patients experienced failure. Isolated pelvic relapse occurred in five patients. Three patients experienced both distant and local relapse. Two patients had isolated distant relapse. Nine failures occurred in patients treated with both external radiotherapy and brachytherapy. Only one failure occurred in those treated with brachytherapy alone. Overall survival and disease-free survival at 5 years were 85% and 92%, respectively. For those treated with both external radiotherapy and brachytherapy, 5-year locoregional control was 95%. For those treated with brachytherapy alone, 5-year locoregional control was 96.4%. There was no significant survival or local control difference between the two groups. Nine patients (9%) treated with both external radiotherapy and brachytherapy developed Radiation Therapy Oncology Group grade 3-4 toxicity. No patient treated with vaginal cuff brachytherapy alone developed grade 3-4 toxicity (P < 0.001). In patients with well-differentiated (grade 1-2) stage IC endometrial cancer, external beam radiotherapy plus brachytherapy versus vaginal cuff brachytherapy alone achieved equivalent local control and survival. However, vaginal cuff brachytherapy alone produced significantly less toxicity.

目的 探讨结肠、直肠手术在治疗卵巢上皮性癌和原发腹膜癌患者的手术指征和治疗效果。方法 对1988年6月～2001年5月在我院妇科接受开腹手术同时行结肠、直肠手术的18例妇科恶性肿瘤进行回顾性分析,其中卵巢上皮性癌16例,原发腹膜癌2例。结果 8例(44.4％)在初次手术中完成结肠、直肠手术,10例(55.6％)在处理复发性癌或者姑息性手术中进行。18例中接受结肠切除或者部分乙状结肠直肠手术,肠吻合术14例,其中3例手法吻合和11例吻合器吻合;4例接受结肠造瘘术患者中,1例于造瘘术后14个月行结肠造瘘还纳术。手术并发症为发热6例,腹泻3例,伤口延期愈合2例以及1例于术后49d因肿瘤进展和突发急性心肌梗塞死亡。17/18例切除肠管者术后病理示肿瘤侵犯至肠浆膜层7例,至浆肌层5例,至粘膜下层3例,至粘膜层2例。7例术后残留癌<2cm,10例>2cm,1例行姑息性手术未切除肠管。术后1年生存率为76％,2年为29％,3年为19％。2例术后存活已超过5年。结论 对卵巢上皮性癌或原发性腹膜癌患者实施结肠、直肠手术是为达到肿瘤细胞减灭或者为缓解肠梗阻症状。对可疑卵巢恶性肿瘤患者术前宜作肠道准备,术中尽量选择肠切除、肠吻合,减少结肠造瘘。对于某些妇科恶性肿瘤患者为提高治疗效果行部分肠管切除是值得的。
