First results of triple-modality treatment combining radiotherapy, chemotherapy, and hyperthermia for the treatment of patients with Stage IIB, III, and IVA cervical carcinoma

Patients with advanced cervical carcinoma are treated routinely with radiotherapy and cisplatin‐containing chemotherapy. It has been shown that hyperthermia can improve the results of both radiotherapy and cisplatin. In the current study, the feasibility and efficacy of the combination of all three modalities was studied in previously untreated patients with cervical carcinoma.

Gynecologic Cancer InterGroup (GCIG) consensus review for endometrial stromal sarcoma.

Abstract Endometrial stromal sarcoma (ESS) accounts for approximately 20% of all uterine sarcomas and presents, at a mean age, around 50 years of age. Half of the patients are premenopausal. ESS often manifests as an endometrial polyp and 60% of cases present with FIGO stage I disease. The natural history is one of slow growing indolent disease. Typical microscopic findings include a uniform population of endometrial stromal-type cells invading the myometrium and myometrial vessels. Imaging studies cannot reliably diagnose ESS preoperatively, so surgical resection for a presumed fibroid is a common scenario. Hysterectomy is the cornerstone of treatment for localized ESS, but morcellation should be avoided. Systematic lymphadenectomy in ESS does not improve the outcome. Leaving the ovaries in situ does not worsen survival and this is of importance especially for young women. The data support the current practice to administer adjuvant hormonal treatment, although several questions remain, such as optimal doses, regimens (progestins or aromatase inhibitors) and duration of therapy. Repeat surgery for recurrent disease that is indolent and hormone sensitive appears to be an acceptable approach. Systemic treatment for recurrent disease is mainly hormonal.

Weekly docetaxel in metastatic breast cancer patients: No superior benefits compared to three-weekly docetaxel

BACKGROUND In anthracycline-pretreated metastatic breast cancer (MBC) patients, it is unknown whether weekly single-agent docetaxel is preferable to 3-weekly docetaxel regarding its toxicity and efficacy profile. PATIENTS AND METHODS In this multicenter, randomised, open-label phase III trial, 162 patients were randomised to weekly docetaxel (group A) or 3-weekly docetaxel (group B). The primary end-point was tolerability; secondary end-points were efficacy and quality of life (QoL). RESULTS Group A (weekly docetaxel, n=79) experienced less haematological toxicity, with just 1.3% versus 16.9% febrile neutropenia in group B (3-weekly docetaxel, n=77) (p=0.001). Not this difference, but fatigue and general malaise foremost led to more patient withdrawals in group A (24 versus 12 patients, p=0.032), less patients completing treatment (29 versus 43 patients, p=0.014) and reduced dose-intensity (15.6 versus 26mg/m(2)/week, 58% versus 70% of projected dose, p=0.017). As a result, 3-weekly docetaxel was related to better overall survival in multivariate analysis (hazard ratio 0.70, p=0.036), although in univariate analysis efficacy was similar in both groups. Reported QoL was similar in both groups, but less effective treatment with more general toxicity led to less completed QoL forms in group A (65.4% versus 50%, p=0.049). CONCLUSION Weekly docetaxel is less well tolerated than a 3-weekly schedule, due to more non-haematological toxicity, despite less febrile neutropenia. Also, no efficacy benefits can be demonstrated for weekly docetaxel, which may even be inferior based on multivariate analysis. Therefore, a 3-weekly schedule should be preferred in the setting of MBC.

Gynecologic Cancer InterGroup (GCIG) Consensus Review: Uterine and Ovarian Leiomyosarcomas

Objectives The Gynecologic Cancer InterGroup aimed to provide an overview of uterine and ovarian leiomyosarcoma management. Methods Published articles and author experience were used to draft management overview. The draft manuscript was circulated to international members of the Gynecologic Cancer InterGroup for review and comment, and appropriate revisions were made. Results The approach to management of uterine and ovarian leiomyosarcoma management is reviewed. Conclusions Uterine and ovarian leiomyosarcomas are rare and aggressive cancers that require specialized expertise for optimal management.

Gynecologic Cancer InterGroup (GCIG) consensus review for high-grade undifferentiated sarcomas of the uterus

Abstract High-grade undifferentiated sarcomas (HGUSs) are rare uterine malignancies arising from the endometrial stroma. They are poorly differentiated sarcomas composed of cells that do not resemble proliferative-phase endometrial stroma. High-grade undifferentiated sarcomas are characterized by aggressive behavior and poor prognosis. Cyclin D1 has been reported as a diagnostic immunomarker for high-grade endometrial stromal sarcoma with an YWHAE-FAM22 rearrangement. YWHAE-FAM22 endometrial stromal sarcomas (ESS) represent a clinically aggressive subtype of ESS classified as high-grade endometrial sarcomas, and its distinction from the usual low-grade ESS with JAZF1 rearrangement and from HGUS with no identifiable molecular aberration may be important in guiding clinical management. Median age of the patients is between 55 and 60 years. The most common symptoms are vaginal bleeding, abdominal pain, and increasing abdominal girth. Disease is usually advanced with approximately 70% of the patients staged III to IV according to the International Federation of Gynecology and Obstetrics classification. Preferential metastatic locations include peritoneum, lungs, intra-abdominal lymph nodes, and bone. Median progression-free survival ranged from 7 to 10 months, and median overall survival ranged from 11 to 23 months. There is no clear prognostic factor identified for HGUS, not even stage. The standard management for HGUS consists of total hysterectomy and bilateral salpingo-oophorectomy. Systematic lymphadenectomy is not recommended. Adjuvant therapies, such as chemotherapy and radiotherapy, have to be discussed in multidisciplinary staff meetings.

Results of concurrent chemotherapy and hyperthermia in patients with recurrent cervical cancer after previous chemoradiation

Abstract Background: Concomitant hyperthermia has been shown to improve response rate after cisplatin in recurrent cervical cancer in previously irradiated patients. It is unclear whether similar response rates can be obtained in patients with a recurrence after previous platinum-containing chemoradiation. Objective: This study aimed to evaluate the outcome of cisplatin-based chemotherapy with concurrent hyperthermia in patients with recurrent cervical cancer after radiotherapy and cisplatin. Methods: Patients with recurrent cervical cancer after cisplatin-based chemoradiation or neoadjuvant chemotherapy followed by surgery and radiotherapy who were treated with concurrent platinum-based chemotherapy and hyperthermia were eligible for this retrospective analysis. All patients received six or eight weekly platinum-based chemotherapy cycles in combination with six or eight weekly hyperthermia sessions. The time-to-event variables were estimated using Kaplan-Meier analysis. P-values less than 0.05 were considered significant. Results: All 38 evaluable patients were selected from the hyperthermia database in the Academic Medical Centre (Amsterdam) and the Erasmus Medical Centre (Rotterdam). Mean age at relapse was 45.7 years (range 27–74). Median time to recurrence after first-line treatment was 15 months. A total of 27 patients had a local and/or regional recurrence; 11 had disease beyond the pelvis. All planned courses of cisplatin chemotherapy and hyperthermia were administered in 17/38 patients. Median follow-up was 6.5 months. One patient died during treatment; response rate was 4/37 (14%), with one complete response. Overall survival was 23% at 12 months and 4% at 24 months. The incidence of grade 3–4 haematological complications did not exceed 10%. Conclusion: In this retrospective study, concurrent cisplatin and hyperthermia after first-line cisplatin-containing chemoradiation showed poor response and survival. We do not recommend this treatment for recurrence of locally advanced cervical cancer.

Effectiveness of chemotherapy in measurable granulosa cell tumors: a retrospective study and review of literature

Objective Patients with irresectable granulosa cell tumors (GCTs) often receive chemotherapy. The effectiveness of this approach, however, is uncertain. The aim of our study was to assess the response rate to chemotherapy for residual and recurrent inoperable GCT. Methods All consecutive chemotherapy-naive patients in 3 referral hospitals who were treated with chemotherapy for residual or recurrent GCT between 1968 and 2011 were included. Main outcome was the response according to Response Evaluation Criteria in Solid Tumor criteria. A literature search in MEDLINE through PubMed was performed, from inception to August 19, 2013. Results Twenty-seven patients with a GCT who received chemotherapy were identified. Eighteen patients were not evaluable because they had either no measurable disease, or no imaging was performed before and after chemotherapy. One of the 9 evaluable patients (11%) had a complete response, and 1 patient (11%) had a partial response, resulting in a response rate of 22% (95% confidence interval, 0%–49%). Seven patients (78%) had stable disease (range, 2–50 months), and none had progressive disease. Fifteen studies that assessed response rates to chemotherapy on measurable disease in a total of 224 patients showed a response rate of 50% (95% confidence interval, 44%–57%). Strict criteria of response, however, were not uniformly applied in the majority of these published series. Conclusions In the present study, we present only a moderate beneficial effect of chemotherapy in patients with irresectable GCT with measurable disease. Comparison with previous studies is hampered by a lack of standardized response evaluation in the majority of studies. Given the toxicity of platinum-based chemotherapy, administering this treatment should be a well-considered decision.

Diagnostic dilemma in a man with seminoma.

2230 www.thelancet.com Vol 364 December 18/25, 2004 In January, 2003, a 30-year-old student was referred to our centre with a stage 1 seminoma with good prognostic indicators. He had a left orchidectomy and radiotherapy of para-aortic nodes. Because of an elevated -fetoprotein (AFP) both before and after treatment, a microscopically undetected non-seminoma part of the tumour was suspected, and he was entered into our follow up surveillance programme for stage I non-seminoma testicular tumours. AFP is a well established tumour marker for diagnosis, staging, monitoring treatment, follow up, and prognosis in nonseminomatous germ-cell tumours. AFP is normal (under 10 μg/L) in patients with seminoma and an elevated AFP is considered almost diagnostic of nonseminoma tumours. During a year of follow-up, his AFP fluctuated (figure), never rising above 51 μg/L nor decreasing to under 20 μg/L. He had no complaints and physical examination continued to be normal. Liver function tests, hepatitis serology, and imaging studies of the liver were normal. Routine CT scan showed enlarged mediastinal lymph nodes in October, 2003, which showed 2-fluoro-D-2-desoxyglucose uptake on PET scan. To exclude a recurrence of seminoma, a thoracotomy was done and the nodes were removed. The histological diagnosis was a granulomatous inflammation consistent with sarcoidosis. Because he had no symptoms, it was decided not to start any treatment. Diagnostic dilemma in a man with seminoma

Post-operative radiotherapy in patients with early stage cervical cancer

OBJECTIVE The aim of this study is to investigate the impact of treatment policy changes in cervical cancer patients treated with adjuvant (chemo) radiotherapy. METHODS Between 1970 and 2007, 292 patients received adjuvant radiotherapy after a radical hysterectomy with pelvic lymphadenectomy for early stage cervical carcinoma. All patients received pelvic radiotherapy (40 Gy-46 Gy in 1.8 Gy-2 Gy/fraction). Vaginal vault brachytherapy boost (10-14 Gy) was increasingly used for patients with high-risk factors, and since 1993 systematically applied in patients with at least 2 of the 3 risk factors: adenocarcinoma, nodal involvement and parametrial invasion. Cisplatin-based chemotherapy was introduced in this group of patients from 2000. RESULTS The 5-year cumulative risk of local recurrence (CRLR) was 13% (95%CI 9%-17%), resulting in an overall 5-year survival (OS) of 78% (95%CI 83%-73%). Since 1970, the OR for the 5-year locoregional recurrence risk (LRR) decreased from 2.5 to 1.15 (linear-OR=-0.02/year). The OR for the 5-year mortality risk reduced from 2.2 in 1970 to 1.0 in 2007 (linear-OR=-0.03/year). The largest risk reductions were observed before 1990 with a minor rise after 2002. The risk of severe late toxicity reduced from 1.8% to 1.5% (linear-OR=-0.03/year). The addition of concomitant adjuvant chemotherapy since 2000 may have benefited a subgroup of patients with squamous cell carcinoma, but not the patients with adenocarcinoma, and after introduction of chemotherapy the risk of severe late toxicity tripled from 2% to 7%. CONCLUSION Since 1970, tumour recurrence risk and mortality have decreased, as radiation dose increased. The potential benefit of concomitant adjuvant chemotherapy could not be demonstrated in this nonrandomized study.

Prognostic Value of Residual Disease after Interval Debulking Surgery for FIGO Stage IIIC and IV Epithelial Ovarian Cancer

Although complete debulking surgery for epithelial ovarian cancer (EOC) is more often achieved with interval debulking surgery (IDS) following neoadjuvant chemotherapy (NACT), randomized evidence shows no long-term survival benefit compared to complete primary debulking surgery (PDS). We performed an observational cohort study of patients treated with debulking surgery for advanced EOC to evaluate the prognostic value of residual disease after debulking surgery. All patients treated between 1998 and 2010 in three Dutch referral gynaecological oncology centres were included. The prognostic value of residual disease after surgery for disease specific survival was assessed using Cox-regression analyses. In total, 462 patients underwent NACT-IDS and 227 PDS. Macroscopic residual disease after debulking surgery was an independent prognostic factor for survival in both treatment modalities. Yet, residual tumour less than one centimetre at IDS was associated with a survival benefit of five months compared to leaving residual tumour more than one centimetre, whereas this benefit was not seen after PDS. Leaving residual tumour at IDS is a poor prognostic sign as it is after PDS. The specific prognostic value of residual tumour seems to depend on the clinical setting, as minimal instead of gross residual tumour is associated with improved survival after IDS, but not after PDS.
