Hemostatic radiotherapy in carcinoma of the uterine cervix

Objective: To evaluate the treatment of hemorrhagic carcinoma of the uterine cervix with hemostatic radiotherapy (external and intracavitary radiotherapy). Method: Twenty cases of refractory hemorrhagic carcinoma of the uterine cervix receiving hemostatic radiotherapy between April 1987 and May 1992 were analyzed. The age of the patients ranged between 30 and 60 years with a median of 42 years. Results: The mean tumor volume was 130 mm³; all cases were classified as FIGO stage IIb (n = 8), IIIb (n = 11) or IVa (n = 1). Radiotherapy was carried out either by the external or intracavitary technique. The control of hemorrhage was 100% within 12–48 h after radiotherapy. However 85% of patients failed locally in the form of residual, recurrent pelvic or metastatic disease, within 24 months of follow-up. Conclusion:Hemorrhagic cervical cancer has a poor prognosis.     

Chemotherapy rapidly alternating with accelerated radiotherapy for advanced carcinoma of the uterine cervix

The objective of this study was to determine the feasibility of treating patients with advanced cervical carcinoma using a regimen combining chemotherapy with intermittent hyperfractionated teletherapy. Eight patients with advanced cervical carcinoma were treated with bleomycin, ifosfamide and cisplatin, followed by a 5-day course of hyperfractionated external radiation. Three such courses were given at 21-day intervals. Treatment was completed using standard brachytherapy. Seven of the eight patients were evaluable for response; all obtained a complete response. Two patients developed recurrence (one in the pelvis and one distant) and died of disease. One patient died of treatment complications. The remaining four remain alive and free of disease 9–42 months after treatment. The simultaneous use of chemotherapy and intermittent hyperfractionated teletherapy is a promising strategy for the treatment of cervical carcinoma, resulting in a high rate of complete response.     

A phase I study of concurrent cisplatin chemotherapy in patients with carcinoma of the cervix receiving pelvic radiotherapy

The purpose of this study was to evaluate the maximum tolerated dose (MTD) of weekly cisplatin in a sample population of South African patients with cervical carcinoma, when given in combination with radical pelvic irradiation. Patients with cervical carcinoma stage IB2-IIIB (without hydronephrosis) received up to six cycles of cisplatin at weekly intervals. Groups consisting of three patients each were treated at each of the three predetermined dose levels of cisplatin (20, 25, and 30 mg/m(2)). Eighteen patients were treated and evaluated for toxicity. All the patients who received 20 mg/m(2) (n = 3) and 25 mg/m(2) (n = 3) cisplatin had no dose-limiting toxicity (DLT). Four of the 12 patients who were given cisplatin 30 mg/m(2) experienced DLT with rising serum creatinine and declining creatinine clearance. The minimum creatinine clearance was 22 mL/min. The highest serum creatinine was 174 mumol/L. This study showed that a weekly dose of 25 mg/m(2) of cisplatin was the MTD when used in combination with pelvic irradiation for this sample of patients. This dose is lower than the recommended dose of cisplatin 40 mg/m(2)/week. The patients in this study may have reduced tolerance to higher doses of cisplatin, when compared to patients from Western countries.     

Results of radiotherapy alone in the treatment of carcinoma of uterine cervix: a retrospective analysis of 1069 patients

Carcinoma of the uterine cervix is the most common malignancy affecting women in developing countries like India. This retrospective study was made to analyze our results of radiotherapy alone in the treatment of carcinoma cervix. Between January 1996 and December 2001, 1069 patients of carcinoma cervix were treated at our center with external beam radiotherapy (EBRT) and intracavitary radiotherapy (871) or EBRT alone (198). The median dose to point A was 81 Gy. Overall survival (OS), disease-free survival (DFS), and pelvic control at 5 years were 51.8%, 49.4%, and 63.9%, respectively. For the patients who could receive intracavitary radiotherapy (871), the OS, DFS, and pelvic control rates were 60.7%, 58.6%, and 73.5%, respectively. On multivariate analysis, bulk, overall treatment time (OTT) and response to EBRT were found to affect OS and DFS independently. Similarly, OTT, response to EBRT, stage, and age were the factors that influenced pelvic control. Incidence of severe late toxicities (grade 3/4) in the rectum, bladder, small intestine, and skin were 1.1%, 1.2%, 0.2%, and 1.2%, respectively. In developing countries like India, where chemoradiation can be afforded by a minority only, judicious use of radiotherapy still produces satisfactory results with acceptable toxicity. The addition of chemotherapy may be beneficial in patients with adverse prognostic factors.     

Vaginal paravaginal repair with an AlloDerm graft

OBJECTIVE: This study was undertaken to describe outcomes of a technique of vaginal paravaginal repair that used AlloDerm graft (LifeCell, Branchburg, NJ) in women with recurrent stage II or with primary or recurrent stage III/IV anterior vaginal wall prolapse. STUDY DESIGN: This was an observational study. Thirty-three women underwent a vaginal paravaginal repair using AlloDerm graft. Anterior vaginal wall prolapse was staged using the pelvic organ prolapse quantification system preoperatively and every 6 months after surgery. Recurrence of prolapse, changes in functional status (urinary symptoms, prolapse symptoms, and sexual activity), and complications were recorded. Objective failure was defined as recurrent anterior vaginal wall prolapse, stage II or greater, and subjective failure as symptomatic recurrent anterior vaginal wall prolapse. Life-table analysis evaluated objective and subjective failure. Risk factors for recurrent anterior vaginal wall prolapse were evaluated. RESULTS: The mean age was 65.2 years and 93% of the women were white. Preoperatively, 6 women had recurrent stage II, 24 women had stage III, and 3 women had stage IV anterior vaginal wall prolapse. The median length of follow-up was 18 months. Postoperatively, 12 women had asymptomatic stage II anterior vaginal wall prolapse (not beyond the hymen) develop, and 1 woman had symptomatic stage II prolapse develop. Thus, there were 13 (41%) objective failures and 1 (3%) subjective failure. Life-table analysis demonstrated the cumulative probability of an objective failure was 0.24 at 1 year and 0.50 at 2, 3, and 4 years. The cumulative probability of a subjective failure was 0.00 at 1 and 2 years and 0.11 at 3 and 4 years. No risk factors for objective failure were identified. Voiding complaints resolved in 11 of 14 (79%) women (P=.004), incontinence symptoms resolved in 17 of 19 (89%) women (P<.001), and urgency symptoms resolved in 20 of 23 (87%) women (P<.001) (all two-tailed Fisher exact test). Twenty-one women (64%) were sexually active, and none complained of postoperative dyspareunia. Complications included 1 case of febrile morbidity, 1 cystotomy, and 1 anterior wall breakdown secondary to hematoma formation caused by heparin therapy. No other erosions or rejections were seen. CONCLUSION: Vaginal paravaginal repair with AlloDerm graft in women with recurrent stage II or stage III/IV anterior vaginal wall prolapse is safe and has good subjective but only fair objective success within the first 2 years.

Vaginal pessaries for the management of pelvic organ prolapse

Pelvic organ prolapse (POP) is a common condition and is thought to affect approximately 40% of women over the age of 40, with prevalence increasing with age. Although POP is not usually associated with mortality, it can significantly impact quality of life. Management of POP includes, the option of no treatment, conservative and lifestyle management, pessary management or surgery. Options for management should take into consideration the woman's preference, the site of prolapse, lifestyle factors, comorbidities, age, desire for childbearing, previous surgery and whether the patient is sexually active. The risks and benefits of each option should be discussed, and women should be included in decision making. Vaginal pessaries are intravaginal devices that aim to restore prolapsed vaginal compartments to a normal position with aim to relieve symptoms. There are a wide variety of pessaries and these are usually made of plastic or silicone. The most commonly used pessaries in the UK are discussed in this article.     

Prostaglandin-induced cervical dilatation prior to intracavitary radiotherapy for carcinoma of the cervix: a pilot study

The efficacy of 1 mg 16,16-dimethyl-trans-Δ2 prostaglandin E1 (Gemeprost) pessaries in achieving cervical dilatation prior to intracavitary brachytherapy was investigated in 16 post-menopausal women with cervical carcinoma. All had received external beam pelvic radiotherapy in the preceding 6 weeks. Four patients were nulliparous and 12 multiparous (mean parity 1.9). FIGO stages were IB (2), IIA (4), IIB (5), IIIA (1), IIIB (3), IVB (1). The cervical os was assessed before pessary insertion and again at the time of intracavitary insertion. The os was closed in 100% (16/16) of patients before and open in 75% (12/16) of patients after pessary insertion. The maximum size of Hegar dilator passed without mechanical dila-tation was recorded. Mean cervical dilatation was 4.25 H (5.5 H in those with a clinical response). The 12 responding patients had rapid and uncomplicated procedures with no need for additional mechanical dilatation. Both patients in whom attempted mechanical dilatation failed had had previous conization of the cervix. The following mild side-effects were reported: abdominal cramps (43.8%), headache (12.5%) and fever (6.3%). These data support the use of Gemeprost pessaries to achieve cervical dilatation in post-menopausal women undergoing intracavitary brachy-therapy following external beam radiotherapy.     

Stage II endometrial carcinoma: limiting post-operative radiotherapy to the vaginal vault in node-negative tumors

OBJECTIVE: To evaluate the outcomes of patients with node-negative stage II endometrial cancer who received vault brachytherapy without external beam pelvic radiotherapy (EBRT). METHODS: A retrospective review of all stage II endometrioid type endometrial cancer patients referred to Cancer Care Manitoba was undertaken between October 1995 and March 2001. Forty-nine patients were identified with disease confined to the uterus, but not all patients received extended surgical staging (ESS) with pelvic lymphadenectomy. These patients were evaluated for recurrence and morbidity data. RESULTS: Twenty node-negative stage II cancers were identified. Three were treated without adjuvant treatment, 12 received vault brachytherapy and 5 received more conventional treatment with EBRT and vault brachytherapy. No recurrences or deaths occurred in these patients. Mean follow-up was 40 months. No surgical complications were encountered in this group and no morbidity from radiotherapy was observed. CONCLUSIONS: Limiting adjuvant treatment to vault brachytherapy for node-negative stage II endometrial cancer results in less morbidity and excellent survival and is worthy of further investigation.     

A phase I/II study combining radical radiotherapy with concurrent cisplatin in the treatment of advanced squamous cell carcinoma of the cervix

Sixteen patients with advanced cervix cancer have been treated in a phase I/II study of concurrent radiotherapy and cisplatin chemotherapy. The external beam radiotherapy was given as a 'split course' because of initial concerns about acute toxicity. The treatment was well tolerated with all patients completing the prescribed radiotherapy and all patients received the intended four doses of cisplatin. One of 5 patients with stage IVB disease is alive and disease free 35 months after treatment. Six of the 11 patients with disease confined to the pelvis are alive and disease free between 28 and 53 months after treatment. One patient has required surgery for a recto-sigmoid stricture.     

Carbon ion radiotherapy for vaginal malignant melanoma: a case report

Malignant melanoma of the vagina is a very rare neoplasm and resistant to conventional radiotherapy. We report a case of vaginal malignant melanoma that was locally well controlled by carbon ion radiotherapy. A 55-year-old postmenopausal woman presented with abnormal vaginal bleeding. On pelvic and imaging examinations, an irregular mass of the posterior vaginal wall sized 7.5 x 5 x 5 cm, an enlarged right inguinal lymph node, and two lung metastases were observed. Histologic diagnosis based on positive immunostaining for HMB-45 was malignant melanoma. She received dacarbazine-based chemotherapy and carbon ion radiotherapy for vaginal and inguinal tumor sites with 57.6 Gy equivalent dose per 16 fractions using five ports. Six months later, she was also given carbon ion radiotherapy for regrowing lung metastasis with 52.8 Gy equivalent dose per four fractions using four ports. She died 19 months after initial treatment due to brain metastases. The primary irradiated tumor disappeared completely 12 months after initial treatment. The vaginal tumor, right inguinal lymph node, and lung tumor treated with carbon ion radiotherapy did not show any evidence of recurrence until her death. Carbon ion radiotherapy may be of value for vaginal malignant melanoma as a conservative approach.     

Continuous intra-arterial cisplatin combined with radiotherapy in locally advanced squamous carcinoma of the cervix: a Gynecologic Oncology Group pilot study

The high local failure rate in patients with locally advanced carcinoma of the cervix treated with standard radiation has spurred interest in radiosensitization. Cisplatin is the most active single chemotherapeutic agent in squamous carcinoma of the cervix, and is considered to be a radiosensitizer. Based on a previous single-institution study looking at continuous low-dose intra-arterial cisplatin given throughout planned radiation therapy in patients with advanced carcinoma of the cervix, the Gynecologic Oncology Group initiated a limited access pilot study to assess the feasibility of this treatment method for a group-wide study. Patients with locally advanced squamous carcinoma of the cervix and surgically documented negative periaortic lymph nodes were eligible for the study. During surgical staging, the catheters of a totally implantable pump were placed in the internal iliac arteries. The pump was filled with cisplatin which was delivered at 4.5–6.5 mg day⁻¹ continuously throughout both external radiation and brachytherapy. Drug distribution through the catheters was determined using radiolabelled macro-aggregated albumin particles. Three of nine evaluable patients were free of disease at follow-up. Drug distribution was less than optimal through 4.6% of the pump catheters. Five patients had premature discontinuation of the cisplatin for various reasons. These problems resulted in low accrual and subsequent closure of the study. This treatment method is not feasible for a phase III evaluation on a group-wide basis.     

Early clitoral carcinoma successfully treated by radiotherapy and bilateral inguinal lymphadenectomy

Abstract. Jones RW, Matthews JH. Early clitoral carcinoma successfully treated by radiotherapy and bilateral inguinal lymphadenectomy.
A 42 year-old female presented with an early stage IB squamous cell carcinoma involving the clitoris. She was treated with radical radiotherapy to the clitoris and peri-clitoral region and bilateral inguinal lymphadenectomy. The treatment was well tolerated. The vulvar appearance, sensation and orgasmic function have not been impaired. There has been no recurrence during five years of follow-up. Radiotherapy and bilateral inguinal lymphadenectomy are an effective therapeutic option in early stage IB carcinoma involving the clitoris in sexually active females.     

Vaginal reconstruction with a greater omentum–pedicled graft combined with a vicryl mesh after anterior pelvic exenteration. Surgical approach with long-term follow-up

Resection of anterior vaginal wall that occurs with some cases of anterior pelvic exenteration leaves the patient with a small and narrow vagina. This affects their sexual life leading to major psychologic problems, especially in young women. The aim of this study is to evaluate a new technique of vaginal reconstruction following anterior pelvic exenteration with clinical and cytohistologic follow-up. Between March 2002 and November 2004, ten sexually active female patients underwent vaginal reconstruction after radical cystectomy that required en bloc removal of the anterior vaginal wall, with a pedicle graft of greater omentum combined with a vicryl mesh. The mean age of the patients was 38 years. The mean operative time of the reconstructive procedure was 50 min. There were no complications regarding the reconstructive procedure. On follow-up, the neovagina accepted two fingers easily and showed a pink-colored smooth lining. Seven patients reported successful attempts of sexual intercourse. It was concluded that reconstruction of vagina after anterior pelvic exenteration in sexually active women can be done safely with the use of vicryl mesh combined with a pedicled omental graft. It is a simple, reliable, and not time-consuming technique. The long-term follow-up was very beneficial in detection of complete healing, postoperative infections, and hormonal activity of the graft and recurrence of malignancy.     

The prognostic factors for patients with early cervical cancer treated by radical hysterectomy and postoperative radiotherapy

PURPOSE: This study was undertaken to evaluate the efficacy of postoperative radiotherapy (post-OP RT) and to investigate the prognostic factors for early-stage cervical cancer patients who were treated by radical surgery, and the pathological findings suggested a relatively high risk of relapse with surgery alone. MATERIALS AND METHODS: From January 1990 to December 1995, 222 patients with stage IB-IIA cervical cancer, treated by radical surgery and a full course of post-OP RT, were included in this study. The indications for post-OP RT were based on pathological findings, including lymph node metastasis, positive surgical margins, parametrial extension, lymphovascular permeation, and invasion of more than two-thirds of the cervical wall thickness. The radiation dose of external beam was 44-45 Gy to the whole pelvis and 50-54 Gy to the true pelvis. One hundred seventy-two patients also received intravaginal brachytherapy as a local boost. The minimal follow-up period was 2 years. RESULTS: The actuarial 5-year overall and disease-specific survival rates for all patients were 76 and 82%, respectively. The tumor control rate within the pelvis reached 94%, and distant metastasis was the major cause of treatment failure. Univariate analysis of clinical and pathological parameters revealed that clinical stage, bulky tumor size, positive lymph nodes, parametrial extension, and histologic type were significant prognostic factors. After multivariate analysis, only positive lymph nodes (P = 0.01), bulky tumor size (P = 0.02), and parametrial extension (P = 0.05) independently influenced the disease-specific survival (DSS). For patients with lymph node metastasis, the number and location of the nodal involvement significantly affected the prognosis. The 5-year DSS for patients with no, one, and more than one lymph node metastasis were 87, 84, and 61% (P = 0.0001), respectively. Patients with upper pelvic lymph node metastasis had a higher incidence of distant metastasis (50% vs 16% in lower pelvic node group, P = 0.03). In the subgroup of single lower pelvic nodal metastasis, the prognosis was similar to that of patients without lymph node involvement (5-year DSS 85% vs 87%, P = 0.71). CONCLUSION: Our results indicate that post-OP RT can achieve very good local control in stage IB-IIA cervical cancer patients whose pathological findings show risk features for relapse after radical surgery. The prognostic factors for treatment failure identified in this study can be used as selection criteria for clinical trials to test the effects of other adjuvant treatments, such as chemotherapy. Patients with a single lower pelvic lymph node metastasis have a relatively good prognosis and may not need adjuvant treatment beyond radiation therapy.
