Fertility Preservation for Patients with Malignant Disease. Guideline of the DGGG, DGU and DGRM (S2k-Level, AWMF Registry No. 015/082, November 2017) - Recommendations and Statements for Girls and Women.

AIM: The aim of this official guideline published by the German Society of Gynecology and Obstetrics (DGGG) and coordinated with the German Society of Urology (DGU) and the German Society of Reproductive Medicine (DGRM) is to provide consensus-based recommendations, obtained by evaluating the relevant literature, on counseling and fertility preservation for prepubertal girls and boys as well as patients of reproductive age. Statements and recommendations for girls and women are presented below. Statements or recommendations for boys and men are not the focus of this guideline. METHODS: This S2k guideline was developed at the suggestion of the guideline commission of the DGGG, DGU and DGRM and represents the structured consensus of representative members from various professional associations (n = 40). RECOMMENDATIONS: The guideline provides recommendations on counseling and fertility preservation for women and girls which take account of the patient's personal circumstances, the planned oncologic therapy and the individual risk profile as well as the preferred approach for selected tumor entities.

Systematic review of anti-inflammatory agents for the management of oral mucositis in cancer patients.

PURPOSE: The aim of this project was to review the available literature and define clinical practice guidelines for the use of anti-inflammatory agents for the prevention and treatment of oral mucositis in cancer patients. MATERIALS AND METHODS: A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology. The body of evidence for use of each intervention, in each cancer treatment setting, was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, and no guideline possible. RESULTS: Forty-one papers were reviewed. There was sufficient evidence to recommend the use of benzydamine mouthwash for the prevention of oral mucositis in head and neck cancer patients receiving moderate-dose radiation therapy (up to 50 Gy), without concomitant chemotherapy. A new suggestion was developed against the use of misoprostol mouthwash for the prevention of oral mucositis in head and neck cancer patients receiving radiation therapy. Positive results were reported for some other anti-inflammatory agents. However, no guidelines were able to be developed for any other agents due to insufficient and/or conflicting evidence. CONCLUSIONS: The use of anti-inflammatory agents continues to be a promising strategy for the prevention and treatment of oral mucositis. Additional well-designed studies are needed to examine the use of this class of agents for oral mucositis.

Systematic review of amifostine for the management of oral mucositis in cancer patients.

PURPOSE: The aim of this study was to review the available literature from 1966 until December 31, 2010 and define clinical practice guidelines for the use of amifostine for the prevention and treatment of oral mucositis in cancer patients. METHODS: A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology. The body of evidence for the use of amifostine, in each cancer treatment setting was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, or no guideline possible. RESULTS: Thirty papers were reviewed for evidence on amifostine as an intervention for oral mucositis. No guideline was possible for amifostine in any cancer treatment setting due to inadequate and conflicting evidence. CONCLUSION: Review of the amifostine studies for the prevention and treatment of oral mucositis has found insufficient evidence to support its use in any cancer treatment setting for this purpose. Additional well-designed research is needed to clarify the role of amifostine as an intervention for oral mucositis.

Evaluation of different biomarkers to predict individual radiosensitivity in an inter-laboratory comparison--lessons for future studies.

Radiotherapy is a powerful cure for several types of solid tumours, but its application is often limited because of severe side effects in individual patients. With the aim to find biomarkers capable of predicting normal tissue side reactions we analysed the radiation responses of cells from individual head and neck tumour and breast cancer patients of different clinical radiosensitivity in a multicentric study. Multiple parameters of cellular radiosensitivity were analysed in coded samples of peripheral blood lymphocytes (PBLs) and derived lymphoblastoid cell lines (LCLs) from 15 clinical radio-hypersensitive tumour patients and compared to age- and sex-matched non-radiosensitive patient controls and 15 lymphoblastoid cell lines from age- and sex- matched healthy controls of the KORA study. Experimental parameters included ionizing radiation (IR)-induced cell death (AnnexinV), induction and repair of DNA strand breaks (Comet assay), induction of yH2AX foci (as a result of DNA double strand breaks), and whole genome expression analyses. Considerable inter-individual differences in IR-induced DNA strand breaks and their repair and/or cell death could be detected in primary and immortalised cells with the applied assays. The group of clinically radiosensitive patients was not unequivocally distinguishable from normal responding patients nor were individual overreacting patients in the test system unambiguously identified by two different laboratories. Thus, the in vitro test systems investigated here seem not to be appropriate for a general prediction of clinical reactions during or after radiotherapy due to the experimental variability compared to the small effect of radiation sensitivity. Genome-wide expression analysis however revealed a set of 67 marker genes which were differentially induced 6 h after in vitro-irradiation in lymphocytes from radio-hypersensitive and non-radiosensitive patients. These results warrant future validation in larger cohorts in order to determine parameters potentially predictive for clinical radiosensitivity.

A systematic review of trismus induced by cancer therapies in head and neck cancer patients.

PURPOSE: This systematic review represents a thorough evaluation of the literature to clarify the impact of cancer therapies on the prevalence, quality of life and economic impact, and management strategies for cancer-therapy-induced trismus. METHODS: A systematic literature search was conducted with assistance from a research librarian in the databases MEDLINE/PubMed and EMBASE for articles published between January 1, 1990 and December 31, 2008. Each study was independently assessed by two reviewers. Taking into account predetermined quality measures, a weighted prevalence was calculated for the prevalence of trismus. The level of evidence, recommendation grade, and guideline (if possible) were given for published preventive and management strategies for trismus. RESULTS: We reviewed a total of 22 published studies between 1990 and 2008. Most of them assessed the prevalence of this complication, and few focused on management. The weighted prevalence for trismus was 25.4% in patients who received conventional radiotherapy and 5% for the few intensity-modulated radiation therapy studies. No clear guideline recommendations could be made for the prevention or management of trismus. CONCLUSIONS: Newer radiation modalities may decrease the prevalence of trismus compared to conventional radiotherapy. Few studies have addressed the quality of life impact of trismus, and no studies were identified to assess the economic impact of trismus. The few preventive and management trials identified in the literature showed some promise, although larger, well-designed studies are required to appropriately assess these therapies before recommendations can be provided.

Effect of preoperative chemoradiation in addition to preoperative chemotherapy: a randomised trial in stage III non-small-cell lung cancer.

BACKGROUND: Preoperative chemotherapy improves survival in patients with stage III non-small-cell lung cancer (NSCLC) amenable to resection. We aimed to assess the additional effect of preoperative chemoradiation on tumour resection, pathological response, and survival in these patients. METHODS: Between Oct 1, 1995, and July 1, 2003, patients with stage IIIA-IIIB NSCLC and invasive mediastinal assessment from 26 participating institutions of the German Lung Cancer Cooperative Group (GLCCG) were randomly assigned to one of two treatment groups. The intervention group were scheduled to receive three cycles of cisplatin and etoposide, followed by twice-daily radiation with concurrent carboplatin and vindesine, and then surgical resection (those with positive resection margins or unresectable disease were offered further twice-daily radiotherapy). The control group were scheduled to receive three cycles of cisplatin and etoposide, followed by surgery, and then further radiotherapy. The primary endpoint was median progression-free survival (PFS) in patients eligible for treatment after randomisation. Secondary endpoints in patients eligible for treatment after randomisation were overall survival (OS) and the proportion of patients undergoing surgery. Secondary endpoints in patients with tumour resection were the proportion with negative resection margins, the proportion with complete resection, the proportion with histopathological response, and the proportion with mediastinal downstaging. Additionally, exploratory (not prespecified) post-hoc analyses in terms of PFS and OS were done on patients not amenable to resection and on further subgroups of patients undergoing resection. Analyses were by intention to treat. This trial is registered on the ClinicalTrials.gov website, number NCT 00176137. FINDINGS: 558 patients were randomly assigned. 34 patients did not meet inclusion criteria and were excluded. Of 524 eligible patients, 142 of 264 (54%) in the interventional group and 154 of 260 (59%) in the control group underwent surgery; 98 of 264 (37%) and 84 of 260 (32%) underwent complete resection. In patients with complete resection, the proportion of those with mediastinal downstaging (45 of 98 [46%] and 24 of 84 [29%], p=0.02) and pathological response (59 of 98 [60%] and 17 of 84 [20%], p<0.0001) favoured the interventional group. However, there was no difference in PFS (primary endpoint) between treatment groups-either in eligible patients (median PFS 9.5 months, range 1.0-117.0 [95% CI 8.3-11.2] vs 10.0 months, range 1.0-111.0 [8.9-11.5], 5-year PFS 16% [11-21] vs 14% [10-19], hazard ratio (HR) 0.99 [0.81-1.19], p=0.87), in those undergoing tumour resection, or in patients with complete resection. In both groups, 35% of patients undergoing surgery received a pneumonectomy (50/142 vs 54/154). In patients receiving a pneumonectomy, treatment-related mortality increased in the interventional group compared with the control group (7/50 [14%] vs 3/54 [6%]). INTERPRETATION: In patients with stage III NSCLC amenable to surgery, preoperative chemoradiation in addition to chemotherapy increases pathological response and mediastinal downstaging, but does not improve survival. After induction with chemoradiation, pneumonectomy should be avoided. FUNDING: German Cancer Aid (Bonn, Germany).

Ovarian function following pelvic irradiation in prepubertal and pubertal girls and young adult women.

PURPOSE: To analyze the effect of pelvic radiotherapy on ovarian function in prepubertal and pubertal girls and young adult women. PATIENTS AND METHODS: In a retrospective monoinstitutional analysis, patients < 30 years of age at diagnosis were included who had been irradiated between 1979 and 1998. The main tumor types were Hodgkin's disease (38%), Ewing's sarcoma (20%) and nephroblastoma (11%). Patients were classified into three groups according to the position of the ovary in relation to the radiation portals. Group 1 was defined by direct irradiation of both ovaries. Group 2 patients were included with both ovaries potentially located in the radiation portals. In group 3, at least one ovary was not directly irradiated. The median follow-up was 128 months. RESULTS: 16 of 55 analyzed patients were categorized in group 1. In ten of these patients, hormone status was evaluable. The ovarian doses were >/= 15 Gy. Except for one patient treated with 15 Gy all developed hormone failure. Eight of 14 patients of group 2 were evaluable. Seven of these patients developed ovarian failure. 19 of 24 patients in group 3 were evaluable. Nine of these patients developed ovarian failure. The observed difference in the rate of ovarian failure between the groups is statistically significant (p = 0.045). CONCLUSION: All patients receiving > 15 Gy to the ovaries developed hormone failure. In one case of a patient receiving an ovarian dose of 15 Gy, hormone failure was not found. In case of pelvic irradiation excluding at least one ovary, approximately half of the patients developed ovarian dysfunction, probably also due to the effects of polychemotherapy.

Changed adhesion molecule profile of Ewing tumor cell lines and xenografts under the influence of ionizing radiation.

BACKGROUND: Adhesion molecules are involved in cell-cell and cell-matrix interactions and may be informative to characterize intercellular mechanisms of invasion and metastasis. This study was performed to characterize radiation-induced changes in the adhesion molecule profile of Ewing tumor subpopulations on a single cell level. MATERIALS AND METHODS: In the present study, two Ewing tumors were characterized in vitro 4, 24 and 72 hours after radiation with 5 Gy and in vivo in a xenograft model 4, 6 and 15 days after radiation with 30 Gy, together with non-irradiated controls, by five parameter flow cytometry. Directly fluorescence-conjugated antibodies that were directed against adhesion molecules (LFA-1 (CD11a), HCAM (CD44), VLA-2 (CD49b), ICAM-1 (CD54), NCAM (CD56), LECAM-1 (CD62L) and CD86) were used. Annexin V and 7-AAD were used to characterize radiation-induced apoptosis. RESULTS: Tumor cell subpopulations were identified by the expression of adhesion molecules, apoptotic markers and DNA content. Heterogeneous changes of the adhesion molecule profile were identified on tumor cell subpopulations after radiation. The expression of CD11a and CD62L correlated with the expression of apoptosis-associated markers. CONCLUSION: The changes of flow cytometric profile under radiation may potentially correlate with a changed metastatic potential of tumor cell subpopulations.

Combined modality treatment for locally advanced non-small cell lung cancer: preoperative chemoradiation does not result in a poorer quality of life.

The German Lung Cancer Cooperative Group (GLCCG) is assessing the impact of chemoradiation in addition to chemotherapy in the neoadjuvant treatment of stage III NSCLC. After three cycles of cisplatin/etoposide patients receive either hyperfractionated radiotherapy (RT) with concurrent carboplatin/vindesine and then surgery (arm A) versus surgery and then conventional RT (arm B). Quality of life (QL) was assessed throughout therapy using the EORTC QLQ-C30 and EORTC QLQ-LC 13. Of 126 eligible patients, 54 completed treatment. For patients in both treatment arms physical functioning decreased, whereas dyspnoea, fatigue and pain increased from beginning to the end of treatment. For self-assessed QL no statistically significant effect was found in or between the two treatment arms. The combined modality approach with preoperative radio/chemotherapy proves to be feasible in treating locally advanced NSCLC patients without decreasing their subjective QL.

Preoperative chemotherapy with and without additional radiochemotherapy: benefit and risk for surgery of stage III non-small cell lung cancer.

OBJECTIVE: Multi-modality approaches are increasingly employed to improve prognosis in surgically treated stage III non-small cell lung cancer (NSCLC). Risk and benefit of the preoperative therapeutic chemotherapy or combined radiochemotherapy on surgical morbidity and mortality are still a matter of debate. METHODS: In 1995, a national phase III trial was started to compare (arm A) preoperative chemotherapy followed by twice-daily chemoradiation and consecutive surgery, with (arm B) preoperative chemotherapy alone followed by surgery and consecutive radiotherapy. An interim analysis with 277 patients was performed to assess surgical risk and complication rates. RESULTS: of the 358 patients, 273 (71%) underwent thoracotomy, 130 (73%) in arm A and 143 (69%) in arm B. Of the 273 patients undergoing thoracotomy, 168 had stage IIIB disease. Complete resection (R0) was achieved in 212 patients (78%), 104 in arm A (80%) and 108 in arm B (76%) (P=n.s.). There was no difference in the proportion of complex resections between treatment arms (41% in arm A; 48% in arm B). Whilst bronchial stump insufficiency (3.8 vs 2.1%) and bleeding requiring re-thoracotomy (1.5 vs 0.7%) prevailed slightly in arm A, the occurrence of pneumonia divided similar in both treatment arms (4.6 vs 4.9%). Surgical mortality reached 6.1% in arm A (8/130) and 5.6% in arm B(6/143) (P=n.s.). CONCLUSIONS: In both treatment arms, a similar percentage of patients could be forwarded to surgery, even in stage IIIB disease. Bimodality induction seems to be superior with regard to resection rates (R0) (n.s.), but was associated with a higher complication rate, especially bronchial stump insufficiency.
