RESUMEN

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is frequent in lung cancer patients. Here, we report a case with persistent hyponatremia, which suggested malignant SIADH and facilitated an early diagnosis of small cell lung cancer (SCLC). A combined radio-chemotherapy led to a partial remission and resolution of SIADH. An early relapse was indicated by reoccurring severe hyponatremia and increased copeptin levels, which were used as surrogate markers for the antidiuretic hormone (ADH). As palliative immunochemotherapy, together with fluid restriction and solute substitution, were unable to control hyponatremia, treatment with the ADH V2-receptor antagonist tolvaptan was initiated. Over time, the dose of tolvaptan needed to be increased, paralleled by a well-documented exponential increase of copeptin levels. In summary and conclusion, this is a rare case of a secondary failure to tolvaptan with unique documentary evidence of increasing copeptin levels. This observation supports the hypothesis that exceedingly high ADH levels may lead to competitive displacement of tolvaptan from the V2 receptor.

RESUMEN

BACKGROUND: The aim of the study is to investigate how well patients remember the radiologist's name after a radiological examination, and whether giving the patient a business card improves the patient's perception of the radiologist's professionalism and esteem. METHODS: In this prospective and randomized two-centre study, a total of 141 patients with BI-RADS 1 and 2 scores were included. After screening examination comprising mammography and ultrasound by a radiologist, 71 patients received a business card (group 1), while 70 received no business card (group 2). Following the examination, patients were questioned about their experiences. RESULTS: The patients in group 1 could remember the name of the radiologist in 85% of cases. The patients in group 2, in contrast, could only remember the name in 7% of cases (p < 0.001). 90% of the patients in group 1 believed it was very important that they are able to contact the radiologist at a later time, whereas only 76% of patients in group 2 felt that this was a very important service (p < 0.025). A total of 87% of the patients in group 1 indicated that they would contact the radiologist if they had any questions whereas 73% of the patients in group 2 would like to contact the radiologist but were not able to do so, because they could not remember the name (p < 0.001). All questions were analysed with a Cochran-Mantel-Haenszel (CMH) test that took study centre as stratification into account. In some cases, two categories were collapsed to avoid zero cell counts. CONCLUSIONS: Using business cards significantly increased the recall of the radiologist's name and could be an important tool in improving the relationships between patients and radiologists and enhancing service professionalism. TRIAL REGISTRATION: We have a general approval from our ethics committee. The patients have given their consent to this study.

RESUMEN

BACKGROUND: Crizotinib, an inhibitor of the anaplastic lymphoma kinase (ALK), is approved since 2012 in Switzerland for use in ALK-rearranged advanced pretreated non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Here we describe our own experience with crizotinib and ALK testing via fluorescence in-situ hybridization (FISH) in the first 10 ALK-positive patients who were treated in central Switzerland in 2011 on a compassionate use basis. RESULTS: We have demonstrated that FISH testing for ALK can be performed simultaneously with other diagnostic procedures, providing oncologists with results in a timely manner to make informed decisions about patient treatment. The majority of our patients treated with crizotinib had a clinical benefit, and the drug was tolerated well. CONCLUSION: The clinical development of crizotinib has been extremely rapid. Nonetheless, by the time crizotinib was approved, many centers including our own had local testing in place and clinical experience with the drug. This emphasizes the importance of broad clinical studies and compassionate use programs in oncology.

RESUMEN

PURPOSE: Chemotherapy-induced alopecia is very distressing for a patient and may have an impact on treatment decisions. On docetaxel-based therapy, alopecia occurs in a substantial proportion of patients. We aimed to investigate whether two different methods of scalp cooling can prevent hair loss. METHODS: In this open-label, prospective, nonrandomized trial, patients with solid tumors receiving docetaxel in a palliative setting were allocated according to patients' preference to short-term cooling (over 45 min postinfusion) with a Paxman PSC-2 machine (PAX), with cold cap (CC), or no cooling. The combined endpoint was alopecia World Health Organisation (WHO) III or IV or the necessity to wear a wig. Study identifier is Clinicaltrials.gov NCT01008774. RESULTS: Two hundred thirty-eight patients were included in the trial (128 patients PAX, 71 CC, and 39 no cooling). Number of cycles (median 4) and median docetaxel doses were similar across groups (55-60 mg/day on weekly therapy, 135-140 mg/day on 3-weekly therapy). Alopecia occurred with PAX, CC, and no cooling under 3-weekly docetaxel in 23, 27, and 74% and under weekly docetaxel in 7, 8, and 17%, respectively. Overall, cooling (PAX and CC combined) reduced risk of alopecia by 78% (hazard ratio 0.22; 95% confidence interval 0.12 to 0.41). CC and PAX prophylaxis led to the same degree of prevention of alopecia. Adverse events (AE) were reported in 5% (most frequently, sensation of cold), and 30 patients (13%) discontinued cooling measures after cycle 1. CONCLUSIONS: In this first comparison published to date, both PAX and CC offer efficacious protection against hair loss, in particular when docetaxel is administered in a 3-weekly interval.

RESUMEN

PURPOSE: We evaluated the long-term outcome after 1 cycle of adjuvant modified bleomycin, etoposide and cisplatin chemotherapy in patients who underwent orchiectomy for high risk clinical stage I nonseminomatous germ cell tumor of the testis. MATERIALS AND METHODS: Between 1995 and 1999 a consecutive series of 44 patients underwent orchiectomy for clinical stage I nonseminomatous germ cell tumor of the testis, followed by a single postoperative cycle of adjuvant modified bleomycin, etoposide and cisplatin for vascular or lymphatic tumor invasion, and/or a predominance (50% or greater) of embryonal carcinoma. RESULTS: Four of the 44 patients were excluded from analysis. Of the patients 35 had no evidence of disease at a median followup of 99 months (range 60 to 134). One patient with progression after 13 months showed complete remission after 3 cycles of salvage bleomycin, etoposide and cisplatin chemotherapy but he died of pneumonia 4 weeks after the third course. Two patients underwent orchiectomy for contralateral testis cancer at 18 and 42 months, respectively, followed by an additional 3 cycles of adjuvant chemotherapy. They remained relapse-free for 4 and 92 months, respectively. The former patient was lost to followup after 4 months. Two other patients were disease-free at 10 and 31 months, respectively, and were lost to followup thereafter. Late side effects were tinnitus in 3 patients and involuntary childlessness in 3, of whom 2 had cryptorchidism of the contralateral testis. Nine patients fathered children. CONCLUSIONS: One cycle of bleomycin, etoposide and cisplatin effectively decreases the risk of relapse in patients with high risk stage I nonseminomatous germ cell tumor of the testis. It has minimal side effects and can be a valuable alternative to retroperitoneal lymph node dissection.

RESUMEN

PURPOSE: To evaluate the effect of single-agent rituximab given at the standard or a prolonged schedule in patients with newly diagnosed, or refractory or relapsed mantle cell lymphoma (MCL). PATIENTS AND METHODS: After induction treatment with the standard schedule (375 mg/m2 weekly x 4), patients who were responding or who had stable disease at week 12 from the start of treatment were randomly assigned to no further treatment (arm A) or prolonged rituximab administration (375 mg/m2) every 8 weeks for four times (arm B). RESULTS: The trial enrolled 104 patients. After induction, clinical response was 27% with 2% complete responses. Among patients with detectable t(11;14)-positive cells in blood and bone marrow at baseline, four of 20, and one of 14, respectively, became polymerase chain-reaction-negative after induction. Anemia was the only adverse predictor of response in the multivariate analysis. After a median follow-up of 29 months, response rate and duration of response were not significantly different between the two schedules in 61 randomly assigned patients. Median event-free survival (EFS) was 6 months in arm A versus 12 months in arm B; the difference was not significant (P = .1). Prolonged treatment seemed to improve EFS in the subgroup of pretreated patients (5 months in arm A v 11 months in arm B; P = .04). Thirteen percent of patients in arm A and 9% in arm B presented with grade 3 to 4 hematologic toxicity. CONCLUSION: Single-agent rituximab is active in MCL, but the addition of four single doses at 8-week intervals does not seem to significantly improve response rate, duration of response, or EFS after treatment with the standard schedule.
