RESUMO
In children with cancer, the heterogeneity in ototoxicity occurrence after similar treatment suggests a role for genetic susceptibility. Using a genome-wide association study (GWAS) approach, we identified a genetic variant in TCERG1L (rs893507) to be associated with hearing loss in 390 non-cranial irradiated, cisplatin-treated children with cancer. These results were replicated in two independent, similarly treated cohorts (n = 192 and 188, respectively) (combined cohort: P = 5.3 × 10-10, OR 3.11, 95% CI 2.2-4.5). Modulating TCERG1L expression in cultured human cells revealed significantly altered cellular responses to cisplatin-induced cytokine secretion and toxicity. These results contribute to insights into the genetic and pathophysiological basis of cisplatin-induced ototoxicity.
RESUMO
STUDY QUESTION: Which chemotherapeutic agents and body site-specific radiation fields are dose-dependently associated with an increased risk of fertility impairment in long-term female childhood, adolescent and young adulthood (CAYA) cancer survivors? SUMMARY ANSWER: Busulfan, lower abdominal radiotherapy (RT) and total body irradiation (TBI) seem to be associated with fertility impairment at any dose, whereas gonadotoxicity of melphalan and procarbazine is suggested at medium/high (>140 mg/m2) or high dose (>5600 mg/m2) therapy, respectively. WHAT IS KNOWN ALREADY: Several treatment-related fertility deficits, as assessed by both self-reported outcomes and hormonal markers are known to occur following treatment of CAYA cancer. However, knowledge regarding precise dose-related estimates of these treatment-related risks are scarce. STUDY DESIGN, SIZE, DURATION: The current case-control study was nested within the PanCareLIFE cohort study. In total, 1332 CAYA survivors from 8 countries, 9 institutions and 11 cohorts, participated in and contributed data to the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: All participants were female 5-year CAYA cancer survivors. In total, 450 cases (fertility impaired survivors) and 882 matched controls (not fertility impaired survivors) were included. Fertility impairment was defined using both questionnaire data (primary or secondary amenorrhea; use of artificial reproductive techniques; unfulfilled wish to conceive) and hormonal data (FSH and anti-Müllerian hormone (AMH)). Multivariable logistic regression models were used to investigate the effect of (i) alkylating agent exposure, and (ii) dose categories for individual chemotherapeutic agents and for RT-exposed body sites. MAIN RESULTS AND THE ROLE OF CHANCE: A positive dose-effect relationship between cyclophosphamide equivalent dose (CED) score and fertility impairment was found, with survivors with a CED score > 7121 mg/m2 being at a significantly increased risk of fertility impairment (odds ratio (95% CI) = 2.6 (1.9-3.6) P < 0.001). Moreover, cumulative dose variables of the following treatments were significantly associated with fertility impairment: busulfan, carmustine, cyclophosphamide, melphalan, procarbazine, lower abdominal RT and TBI. Busulfan, lower abdominal RT and TBI seem to be associated with fertility impairment at any dose, whereas gonadotoxicity of melphalan and procarbazine is suggested at medium/high (>140 mg/m2) or high dose (>5600 mg/m2) therapy, respectively. LIMITATIONS, REASONS FOR CAUTION: Our study may have been subject to selection bias since data from about half of the original base cohorts were available for the current study. This could impact the generalizability of our study results. WIDER IMPLICATIONS OF THE FINDINGS: We identified survivors at high risk for fertility impairment and, consequently, for a reduced or even absent reproductive life span. Both girls and young women who are about to start anti-cancer treatment, as well as adult female survivors, should be counselled about future parenthood and referred to a reproductive specialist for fertility preservation, if desired. STUDY FUNDING/COMPETING INTEREST(S): This study has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no. 602030. There are no competing interests. TRIAL REGISTRATION NUMBER: n/a.

Due to the considerably improved prognosis of childhood cancer, research regarding the long-term consequences has become highly valuable. The population-based German Childhood Cancer Registry forms the basis of the long-term follow-up of these patients. The cohort comprises over 25,000 patients (with malignant diseases before their 15th birthday) with a current address and who are neither deceased nor lost to follow-up. The current median age is 21 years and 500 individuals are already over 40 years old. All the long-term survivors are contacted every 5 years at the latest and are asked about possible long-term effects. Due to the continued improvement of the prognosis for childhood cancer over the years, such cohorts of long-term survivors have altered in their composition. Corresponding long-term follow-up studies can therefore not easily be compared to one another. This is illustrated by a nested case control study on the possible relationship between the occurrence of second tumors and the therapy undergone for the initial diagnosis. The cohort of long-term survivors in the German Childhood Cancer Registry is highly valuable both for research on long-term effects in Germany as well as for integration into international projects.

BACKGROUND: Survivors of pediatric cancer are at increased risk for medical and psychosocial late effects. This study retrospectively investigated the utilization of oncological and psychosocial care by former adolescent cancer patients (≥ 5 years since cancer diagnosis) in Germany. PATIENTS: Based on data of the German Childhood Cancer Registry (N=1 876 survivors of cancer with an age at diagnosis between 15 and 18 years), the study cohort comprised 820 survivors of adolescent cancer (time since diagnosis: M=13.7, SD=6.0, age at follow-up: M=30.4, SD=6.0 years). METHOD: Survivors of adolescent cancer completed standardized questionnaires measuring symptoms of posttraumatic stress, depression and anxiety as well as items on their utilization of medical and psychosocial care. RESULTS: More than a quarter (26.2%) of the survivors was no longer attending regular oncological follow-up assessments. Less than half of the survivors (44.4%) had received psychosocial care, mostly during their in-patient cancer treatment and their post-acute rehabilitation phase. Out of 184 survivors showing clinically relevant symptoms of posttraumatic stress, anxiety and/or depression at time of the study, 12.0% received psychosocial care and 13.6% took psychotropic medication. CONCLUSION: It should be studied further why only a small proportion of the survivors showing clinically relevant symptoms received psychosocial or psychopharmacological treatment. Systematic oncological follow-up assessments should take psychological late effects into greater account.

BACKGROUND: The objective of this paper is to provide information about the quality (e.g. completeness, response) of long-term surveillance in German paediatric oncology and haematology based on the structures implemented by the German Childhood Cancer Registry (GCCR). METHODS: The GCCR contacts parents or patients to collect and update information on a minimal set of follow-up health status data (e.g. late relapses, subsequent neoplasms, current address) and exchanges this information regularly with the appropriate clinical trials. RESULTS: Between 2006 and 2010, GCCR approached a total of about 20,000 patients (contact at the age of 16 years, inquiry concerning the health status) in the context of long-term surveillance. 11,000 addresses of former patients had to be researched via municipal registrar's offices. The response rates ranged from 56% to 68%, the research in municipal offices provided 93-96% valid addresses. Of 46,115 patients diagnosed between 1980 and 2009, 25,283 are in long-term surveillance in 2010. DISCUSSION: Long-term surveillance requires considerable logistic effort at GCCR and requires that thousands of letters be mailed each year in order to ensure regularly updated information. Long-term surveillance is indispensable for a better understanding of late effects, subsequent neoplasms and quality of life of former childhood cancer patients.

The treatment of 3 non-ruptured tubal pregnancies by hysteroscopic intratubal injection of methotrexate was reported. In all 3 cases the beta-hCG serum levels decreased after injection during clinical, serological and sonographical control. In 2 patients the tubes were patent at a later control. In selected cases the intratubal administration of methotrexate via hysteroscopy is an alternative minimal invasive treatment.

The interstitial fluid space (IFS) response to hemorrhagic shock (HS)-induced metabolic acidosis is reported. Prenodal skin lymph was used as a mirror of IFS changes. Twenty-three conditioned dogs had a reservoir HS insult followed by resuscitation with shed blood, crystalloid solution containing a total of 6.5 milliequivalents of sodium per kilogram of body weight and 250 milliliters of autologous banked blood. Prenodal skin lymph pH, oxygen tension (pO2), carbon dioxide tension (pCO2), bicarbonate level (HCO3) and flow rate measured before shock, during HS and in postresuscitation in 17 dogs in group 1 were compared with simultaneous samples of central venous blood. Peripheral venous values were not measured in dogs in group 1 to preclude any effects that local dissection might have on prenodal skin lymph. Six dogs in group 2 underwent the same HS and resuscitation model; the sequential changes in central mixed venous pH and lymphatic pH were compared with peripheral venous pH. HS caused metabolic acidosis; in group 1, the mixed venous pH decreased to 7.16 and in group 2, the peripheral venous pH decreased to 7.03. In contrast, the prenodal skin lymph pH in both groups was maintained at PS levels (7.51). Mixed venous pO2 decreased sharply with HS, whereas skin lymph pO2 was maintained. Maintained prenodal skin lymph pH and pO2 during HS-induced metabolic acidosis implies that the IFS undergoes stoichiometric changes. This facilitates the preferential adherence of highly charged proteins, like albumin, to the matrix to maintain cellular homeostasis.

The effects of cisplatin and 5-fluorouracil on wound breaking strength and the rate of closure of an orocutaneous fistula were studied in 80 male rodents. Treatment rats received a total of 4.6 mg/kg cisplatin and 62 mg/kg 5-fluorouracil in six doses/12 days; control rats received 0.9 per cent saline. After treatment, 30 treatment and 30 control rats received a dorsal skin incision which was closed primarily. Wound breaking strength were tested at one, three and five weeks in ten rats from each group. An 8-mm orocutaneous fistula was made in the remaining ten treatment and ten control rats; the rate of closure was noted weekly. Cisplatin and 5-fluorouracil did not significantly impair wound breaking strength at one, three, or five weeks. The rate of closure of the orocutaneous fistula was not effected by cisplatin/5-fluorouracil. The chemotherapy caused severe facial cellulitis and death in four orocutaneous fistula rats. Combined chemotherapy with cisplatin and 5-fluorouracil should not interfere with planned surgical care of head and neck tumors. Concomitant antibiotic coverage, however, is advocated.

The effects of hydroxyethyl starch (Hespan) resuscitation on serum and lymphatic proteins following hemorrhagic shock were studied in 34 splenectomized dogs. Following shock, five randomly assigned treatment groups received the shed blood plus 50 mL/kg of salt solution (RL) or RL with varying concentrations (0.22-1.5 gm/kg) of Hespan. Each dog received 50 ml/kg/d of the test solution for three days after shock. Prothrombin time, partial thromboplastin time, thrombin time, total serum protein, albumin, globulin, and coagulant protein activity of fibrinogen, prothrombin, and factor VIII were measured before shock, at the end of shock, following resuscitation, and on day 3; thoracic duct lymph values were obtained on day 3. Hespan-supplemented resuscitation lowered all serum proteins including albumin, globulin and coagulant proteins; concomitantly, the lymph protein rose after Hespan resuscitation. This decrease in serum proteins and rise in lymph proteins parallels similar results after albumin resuscitation in man and animals and suggests that Hespan induces an oncotically controlled extravascular protein relocation. Further studies on the significance of these findings need to be conducted.

We report about 58 ultrasonographically guided transcervical chorionic villus biopsies from January 1985 to November 1987. Maternal age greater than 35 years (n = 28), followed by trisomy 21 or 18 (n = 10) were the mean indications. Biochemically evaluation of storage diseases (n = 6) and genomically DNA-analysis because of phenylketonuria (n = 2) were combined in each case with cytogenetic diagnosis. In the other cases certain indications were the reasons for biopsy. In 52 of 58 cases we were successful in biopsies and diagnoses. In the other 6 biopsy specimen we didn't found chorionic villi. 3 abortions we observed up to day 3 after operation (n = 3) and after 6 weeks (n = 1). Pathological findings were 1 trisomy 16, 1,47,XYY-karyotype and 1 embryo with phenylketonuria. Another reason for termination of pregnancy was male karyotype in a Morbus Duchenne-risk and 1 risk for Rett-syndrome. Meanwhile 30 healthy babies were born.

Chemotherapy for malignant disease is usually deferred for three weeks postoperatively to prevent interference with wound healing. Recently, aggressive perioperative combination chemotherapy has improved survival rates in patients with germ cell tumors. Facial dehiscence at one month in a young man on combination chemotherapy for a pure choriocarcinoma prompted this experimental study. Laboratory rats receiving bleomycin, perioperatively and a combination of bleomycin, etoposide and cisplatin had a significant decrease in wound breaking strength five weeks after injection. These data suggest that patients receiving bleomycin alone or in combination should have fascial closure with nonabsorbable sutures.

The efficacy of supplemental fresh frozen plasma (FFP) therapy after massive packed red cell (PRBC) replacement for hemorrhagic shock was studied in 22 conditioned dogs. Ten dogs were randomized to received FFP, balanced electrolyte solution (BES), and PRBC, while 12 dogs received BES and PRBC. Coagulation factor activity for Factors I, II, V, VII and VIII, as well as antithrombin III (AT III), prothrombin time, partial thromboplastin time, and thrombin time, were measured at preshock, postshock, postresuscitation, and postshock day two. All coagulation factor activities fell with shock and decreased further with resuscitation in both groups. Factor II (a procoagulant) and AT III (an anticoagulant) fell significantly less after resuscitation in the plasma dogs; otherwise, no postresuscitation differences were seen. The changes in factor activity from postresuscitation until day two reflected factor half life and molecular weight, independent of FFP therapy. These data show that prophylactic FFP therapy does not efficiently restore coagulation activity. Consequently, routine FFP therapy for its procoagulant effects after hemorrhagic shock should be abandoned pending controlled studies in man.

Prior work showed that albumin resuscitation in man leads to decreased coagulation activity and coagulation protein content. These observations were tested in 20 splenectomized dogs shocked by control hemorrhage and resuscitated with the sequential infusion of: (1) 20 ml/kg balanced electrolyte solution (BES) or 5% albumin/BES; (2) shed blood; (3) 30 ml/kg BES or 5% albumin/BES; (4) 250 ml blood stored from the time of splenectomy. Either BES or 5% albumin/BES was given for the next 3 days. Coagulation activity (fibrinogen, plasminogen, factor VIII, and prothrombin) and coagulation protein content (factor VIII by specific canine antigen) were measured preshock, post resuscitation, and daily for 3 days. Albumin resuscitation significantly (p = greater than 0.05) reduced coagulation activity of fibrinogen (423 +/- 145 vs. 274 +/- 80 mg/dl SD), factor VIII:C (64 +/- 24 vs 42 +/- 16% SD), prothrombin (195 +/- 44 vs. 141 +/- 22% SD) but did not alter CPC of factor VIII:RAg (142 +/- 83 vs. 156 +/- 141% SD). Lower coagulation activity after 5% albumin/BES resuscitation in conjunction with no change in factor VIII:RAg content which is produced by the vascular endothelium suggest that impaired hepatic synthesis may lead to the reduced coagulation activity after albumin resuscitation.

Among 1521 malignant extracranial tumours, 64 metastases (4.2%) were found in the pituitary. The most frequent occurrence was found for carcinomas of the breast (21.4%) and for bronchial malignomas (5.9%). A statistically significant difference with regard to the location in the anterior and the posterior lobe was not found in our own patients. A remarkable fact is the high degree of affection of the pituitary gland in case of malignant melanomas.
