Familial adenomatosis polyposis-related desmoid tumours treated with low-dose chemotherapy: Results from an international, multi-institutional, retro…
2019
[Introduction] Desmoid tumour (DT) is a locally aggressive fibroblastic proliferative disease representing the most common extraintestinal manifestation of familial adenomatosis polyposis (FAP). As data on the activity of chemotherapy in these patients are limited, we examined the outcomes of patients treated with low-dose methotrexate (MTX)+vinca alkaloids (vinorelbine or vinblastine).
External validation of a prognostic model estimating the survival of patients with recurrent high-grade gliomas after reirradiation
2015
PURPOSE: We aimed to validate a controversial prognostic model for the survival of relapsed malignant glioma patients after reirradiation with an independent, multicentric patient cohort.METHODS AND MATERIALS: A total of 165 malignant glioma patients underwent reirradiation at 4 different institutions between 1994 and 2012. Twenty-two patients had a good (score 1), 44 had a moderate (score 2), and 99 had a poor prognosis (score 3 or 4). Four statistical methods were used to validate the prognostic model: First, we compared survival according to prognostic group in the construction and the validation cohort by visual comparison of the respective Kaplan-Meier plots. Second, discrimination was…
Survival of cervical cancer patients in Germany in the early 21st century: A period analysis by age, histology, and stage
2012
Background: Population-based studies on endometrial cancer providing survival estimates by age, histology, and stage have been sparse. We aimed to derive most up-to-date and detailed survival estimates for endometrial cancer patients in Germany. Methods: We used a pooled German national dataset including data from 11 cancer registries covering a population of 33 million people. 30,906 patients diagnosed with endometrial cancer in 1997-2006 were included. Period analysis was performed to calculate 5-year relative survival (RS) in 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age-adjustment was performed using five age groups (15-44, 45-5…
Effects of anemia correction with epoetin beta in patients receiving radiochemotherapy for advanced cervical cancer
2007
Patients with cervical cancer frequently suffer from anemia. This two-stage, adaptive-design study investigated the effect of anemia correction with epoetin beta on treatment outcomes. Patients with stage IIB–IVA cervical cancer received radiochemotherapy (RCT) and were randomized to epoetin 150 IU/kg three times weekly (n = 34) or standard care (control; n = 40) for up to 12 weeks. Primary end point for stage 1 aimed to establish a correlation between anemia correction and treatment failure (no complete response or relapsing within 6 months after RCT initiation) as a proof of concept before moving into stage 2. Secondary end points included progression/relapse-free survival, overall surviv…
About invasive cervical cancer: a French population based study between 1998 and 2010
2015
Abstract Objectives The new French cancer plan provides the implementation of organized screening. To make an assessment of the situation, we aim to describe clinical, tumor and survival characteristics of patients with invasive cervical cancer. Study design Data on women suffering from invasive cervical cancer and diagnosed from 1998 to 2010 were provided by the Cote d’Or breast cancer registry. Survival was described using the Kaplan–Meier method and prognostic factors of survival were estimated in a Cox proportional hazard model. Results On the whole, 1019 cancers have been collected including 311 (30.5%) invasive ones. The peak incidence was between 40 and 49 years, with an average age …
Maternal caesarean section infection (MACSI) in Sierra Leone: a case-control study.
2020
Sierra Leone is the country with highest maternal mortality and infections are the underlying cause in 11% of maternal deaths, but the real burden remains unknown. This study aims to determine the incidence and risk factors of surgical site infection (SSI) post-caesarean section (CS) in women admitted to Princess Christian Maternity Hospital (PCMH) in Freetown, Sierra Leone. A prospective case-control (1:3 ratio) study was implemented from 1 May 2018 to 30 April 2019 and 11 women presenting with suspected or confirmed infection post-CS were screened for inclusion as a case. For each case, three patients undergoing CS on the same day and admitted to the same ward, but not presenting with SSI…
Morbidity after pelvic exenteration for gynecological malignancies: a retrospective multicentric study of 230 patients.
2013
ObjectiveOur study purpose was to evaluate morbidity and postoperative mortality in patients who underwent pelvic exenteration (PE) for primary or recurrent gynecological malignancies.MethodsWe identified 230 patients who underwent PE, referred to the gynecological oncology units of 4 institutions: Charitè University in Berlin, Friedrich-Schiller University in Jena, S. Orsola-Malpighi University in Bologna, and Catholic University in Rome and in Campobasso.ResultsThe median age was 55 years. The tumor site was the cervix in 177 patients, the endometrium in 28 patients, the vulva in 16 patients, and the vagina in 9 patients. Sixty-eight anterior, 31 posterior, and 131 total PEs were performe…
Surgical therapy of recurrent vulvar cancer.
2005
Objective The success of various surgical interventions in 201 cases with recurrent vulvar carcinoma was examined in the light of patients' pretreatment, surgical therapy, plastic reconstruction, and postoperative disease course. Study design A databank of standardized clinical data was analyzed using statistical procedures. Results Therapy was selected on an individual basis according to tumor status. Recurrence at a site distant from the primary tumor, particularly in the inguinal region, indicated a markedly unfavorable prognosis. In contrast, tumors recurring locally did not exhibit any significant differences. Plastic surgery reconstruction led to improvements with respect to operabili…
Reconstructive plastic surgery in the treatment of vulvar carcinomas
2005
Abstract Objective The results obtained using plastic surgery reconstruction in 207 patients with a primary or recurrent vulvar carcinoma were analyzed with regard to the surgical procedures applied, pre-treatment and post-operative findings, along with the long-term oncological disease course. Study design Standardized data concerning the surgical procedures applied and clinical factors were collected in a databank and statistically analyzed. Results The flaps employed were termed either ‘local' (cutaneous or fasciocutaneous; n =84) or ‘regional' (myocutaneous, n =123). For local flaps, the rate of secondary healing was 31%, dropping to 20% for regional flaps. Such healing disturbances oft…
Prospective randomized comparison of conventional instruments and the Harmonic Focus(®) device in breast-conserving therapy for primary breast cancer.
2011
Abstract Background In recent years, surgeons have utilized Harmonic instruments to perform breast cancer resection. Retrospective and prospective studies have demonstrated that the use of this surgical device for mastectomy and axillary dissection can reduce perioperative blood loss, seroma formation, and duration and total amount of drainage. No study has analyzed the feasibility of Harmonic instruments in breast-conserving surgery. We conducted a prospective, randomized clinical trial comparing Harmonic instrument and conventional surgery in the performance of breast-conserving surgery and axillary procedures to determine differences in surgical procedures, postoperative outcome, and com…
