Over the past 24 years, research groups in eight different countries have conducted 28 independent evaluation studies on Integrated Psychological Therapy (IPT) including 1,329 schizophrenia patients. The present study examines the effectiveness of IPT under different treatment conditions by means of a meta-analytic review. The most salient results indicate favourable mean effect sizes for IPT in comparison to control groups (placebo-attention conditions, standard care). Moreover, the superiority of IPT continues to increase during an average catamnestic phase of 8.1 months. The method obtains similarly favourable effects in different functional areas (neurocognition, social behaviour, psychopathology) and different assessment formats (expert ratings, self-reports, psychological tests). The comparison of different settings of IPT and control groups shows the superiority of IPT in any given therapy or site condition. The analysis of subsamples of inpatients, outpatients, and patients in varying rehabilitation phases reveals similarly favourable effects. Comparing only high-quality studies yields comparable results. In summary, the present meta-analysis corroborates evidence that IPT is an 'empirically validated treatment' according to American Psychiatric Association guidelines.
AIM: The radical surgical approach in the treatment of vulvar cancer patients has led to a favorable prognosis for the majority of the patients with early stage squamous cell cancer. However, the morbidity is impressive, leading to more individualized treatment. The aim of this review is to give an overview of the management of vulvar cancer. METHODS: We have reviewed the literature on the modifications in treatment of vulvar cancer with the emphasis on surgery and radiotherapy for primary disease. RESULTS: While surgery is the cornerstone of treatment for early stage squamous cell vulvar cancer (with wide local excision and uni- or bilateral inguinofemoral lymphadenectomy via separate incisions as standard treatment), until now there has been a limited role for primary radiotherapy although this may be an attractive alternative for the inguinofemoral lymphadenectomy in the future. The sentinel lymph node procedure with the combined technique (preoperative lymphoscintigraphy with (99m)technetium-labeled nanocolloid and Patente Blue) is a promising staging technique for patients with vulvar cancer. The clinical implementation of the sentinel lymph node procedure and the role of additional histopathological techniques of the sentinel lymph nodes have to be investigated. In advanced vulvar cancer, chemoradiation followed by surgery should be regarded as the treatment of first choice for these patients. CONCLUSIONS: Due to the rarity of vulvar cancer it is quite clear that further studies will have to be performed by international collaborative groups. The sentinel lymph node procedure and primary radiotherapy are promising methods to reduce morbidity of treatment, but their safety needs to be studied in clinical trials.
BACKGROUND AND AIMS: The Union Internationale Contre le Cancer and American Joint Committee on Cancer classification propose that pN(0)-classified colorectal lymphadenectomy specimens will ordinarily include 12 or more tumor-negative lymph nodes. We performed a clinical trial to investigate whether a short-term preoperative radiotherapy (5x5 Gy) leads to a reduction of the number of lymph nodes in rectal cancer specimens after total and partial mesorectal excision (TME and PME, respectively). MATERIALS AND METHODS: Within a 5-year period, 28 (15%) of 148 rectal cancer patients underwent hypofractionated preoperative radiotherapy in this monocenter study, whereas 120 patients (85%) underwent TME/PME surgery alone. The main criterion was the number of lymph nodes in TME/PME specimens. We used a stratified one-sided Wilcoxon-Mann-Whitney test to test for a significant difference in the number of lymph nodes, stratifying for tumor location and postoperative tumor stage. Patients who were suspected of having any alterations in the number of pelvic lymph nodes were excluded from the study. RESULTS: Fewer lymph nodes were detected in the TME/PME specimens of patients who received hypofractionated preoperative radiotherapy compared to patients who underwent TME/PME surgery alone (12 detectable lymph nodes vs 15; p=0.0005). Tumor location (p=0.095) and tumor stage (p=0.093) did not significantly influence the number of lymph nodes in this study. CONCLUSIONS: We conclude that a 5x5 Gy short-term preoperative radiotherapy leads to a reduction in the number of lymph nodes in TME/PME specimens. Because neoadjuvant therapy in rectal cancer for T(2) and T(3) tumors has advanced a new therapeutic standard procedure, in the future, less lymph nodes will be detected in TME/PME specimens. This might influence the required number of lymph nodes in current staging systems for rectal cancer in the future.
