RESUMEN

BACKGROUND: The prognosis of patients with progressive or recurrent high-grade gliomas (HGGs) after surgery remains poor. Iodine-125 brachytherapy is emerging as a salvage method for the treatment of gliomas. This study aimed to investigate whether permanent iodine-125 brachytherapy could be used as an effective therapeutic method even without radiotherapy and/or chemotherapy for progressive or recurrent HGG after gross total resection. METHODS: Between March 2004 and August 2016, 58 patients with progressive or recurrent HGG after gross total resection were included in this study. Twenty-nine patients underwent radiotherapy and/or chemotherapy and then permanent iodine-125 brachytherapy (SRCI group). Twenty-nine patients underwent permanent iodine-125 brachytherapy alone (SI group). Follow-up was carried out at 1, 3, and 6 months and then at 1, 2, 3, and 5 years after iodine-125 implantation. The median overall survival (OS) and progression-free survival (PFS), procedure-related complications and clinical outcomes were evaluated. RESULTS: No procedure-related fatal events happened. The temporary morbidity rate was 11.9%. The median OS and PFS for patients in the SI group were 22 and 8 months compared with 21 and 7 months in the SRCI group. No significant differences were found. Age and Karnofsky Performance Status (KPS) were independent prognostic factors for OS. Age, KPS and histology were independent prognostic factors for PFS. CONCLUSIONS: Permanent iodine-125 brachytherapy could be used as an effective therapeutic method even without radiotherapy and/or chemotherapy for progressive or recurrent HGG after gross total resection.

RESUMEN

BACKGROUND: Patients with recurrent oropharyngeal cancer often require extensive salvage surgery. For patients with clinically N0 necks, the indication for concurrent neck dissection remains unclear. This study aimed to determine predictors, prevalence, and distribution of nodal disease in patients treated with salvage oropharyngectomy. METHODS: In a case series with data collection at a single tertiary academic National Cancer Institute (NCI)-designated comprehensive cancer center, this study analyzed patients treated with prior radiation or chemoradiation who had persistent, recurrent, or second primary squamous cell carcinoma of the oropharynx requiring oropharyngeal resection between 1998 and 2017 (n = 95). Clinical and oncologic characteristics and treatment outcomes were collected, and statistical analyses were performed. RESULTS: The overall rate of nodal positivity was 21% (24/95), and the rate of occult nodal disease was 6% (4/65). Ipsilateral and contralateral level 2 were the most common areas harboring positive nodes. Bivariate analysis showed female sex (p = 0.01), initial overall stage (p = 0.02), and N status (p = 0.03), as well as recurrent overall and T stage (p = 0.05) to be predictors of nodal disease. In the multivariate analysis, recurrent T stage continued to be significantly predictive of pathologic nodal disease. Both computed tomography (CT) and positron emission tomography-CT were moderately accurate in predicting nodal disease in the salvage setting (area under the curve, 0.79 and 0.80, respectively). CONCLUSION: Occult nodal disease is observed in few patients undergoing salvage oropharyngeal resection. This study identified factors predictive of nodal disease in patients undergoing salvage oropharyngectomy and appropriate diagnostic tests in this setting.

RESUMEN

BACKGROUND: Patients undergoing salvage surgery for recurrent head and neck squamous cell carcinoma are at high risk of postoperative complications due to the adverse effects of radiotherapy on wound healing. Malnutrition is an additional risk factor and we tested the hypothesis that preoperative administration of immunonutrition would decrease complications in this high risk population. METHODS: This single armed study with historical control included consecutive patients undergoing salvage surgery for recurrent head and neck squamous cell carcinoma. We compared outcomes before and after implementation of preoperative immunonutrition and adjusted the regression analysis for gender, age, body mass index, Nutritional Risk Screening (NRS 2002), tobacco and alcohol consumption, tumor localization, tumor stage, and type of surgery. The primary endpoint was overall complications from surgery within a follow-up of 30 days. RESULTS: Ninety-six patients were included (intervention group: 51, control group: 45). Use of preoperative immunonutrition was associated with a significant reduction in overall complications (35% vs. 58%, fully-adjusted odds ratio 0.30 (95%CI 0.10-0.91, p = 0.034). Length of hospital stay was also significantly reduced (17 days vs. 6 days, p = < 0.001). No differences in mortality and hospital readmission were found. These results remained robust in multivariate analysis. CONCLUSIONS: In patients undergoing salvage surgery for recurrent head and neck squamous cell carcinoma, preoperative immunonutrition exhibited favorable effects on the complication rate and consequently reduced the length of hospital stay. By improving both tissue regeneration and immune response, immunonutrition may help to improve surgical outcomes in this high-risk population.

RESUMEN

BACKGROUND: Current guidelines of the National Comprehensive Cancer Network and the European Society of Medical Oncology recommend regorafenib or trifluridine/tipiracil (TAS-102) for third-line therapy of metastatic colorectal cancer (mCRC). We evaluated the impact of regorafenib and TAS-102 treatment on skeletal muscle dynamics and sarcopenia. PATIENTS AND METHODS: This retrospective analysis was based on unselected, consecutive mCRC patients treated with regorafenib and/or TAS-102 during third or later line of therapy at our tertiary-care cancer center in Salzburg, Austria. The skeletal muscle index (SMI, cm2/m2) and sarcopenia were evaluated from cross-sectional computed tomographic images at the level of the third lumbar vertebra. RESULTS: Between January 2013 and April 2018, a total of 45 patients had received regorafenib and/or TAS-102. At initial mCRC diagnosis and at initiation of third-line therapy, 24% and 54% of patients presented with sarcopenia. A statistically significant skeletal muscle loss was observed during regorafenib treatment (median SMI change: -2.75 cm2/m2 [-6.3%]; P < .0001), which was not the case during TAS-102 therapy (-1.5 cm2/m2 [-3.5%]; P = .575). Furthermore, subclassification of patients into 3 groups-normal muscle mass, stable sarcopenia, and new-onset sarcopenia-at initiation of third-line therapy permitted discrimination of overall survival, with 1-year overall survival rates of 61%, 29%, and 16%, respectively (P = .04). CONCLUSION: The frequency of sarcopenia increases during the course of mCRC and negatively affects survival. In contrast to TAS-102, regorafenib is associated with increased skeletal muscle loss during mCRC treatment and should therefore be used with caution in mCRC patients with preexisting sarcopenia or a history of recent weight loss.

RESUMEN

PURPOSE: Limited pelvic nodal relapse of prostatic cancer is a paramount challenge for locoregional salvage treatments. Salvage whole pelvis radiation therapy as considered in the BLINDED trial is an attractive option, but there are concerns about its toxicity. This article describes early toxicity with the technique. METHODS AND MATERIALS: BLINDED was a prospective multicenter phase 2 trial investigating high-dose salvage pelvic irradiation with an additional dose to the fluorocholine-based positron emission tomography-positive pelvic lymph nodes, combined with 6-month androgen blockade. The prescribed dose was 54 Gy in 1.8 Gy fractions with up to 66 Gy in 2.2 Gy fractions to the pathologic pelvic lymph nodes. Early toxicity was defined as toxicity until 1 year after radiation therapy. Patients quality of life was assessed using the European Organisation for Research and Treatment of Cancer questionnaires (QLQ-C30 and QLQ-PR25). RESULTS: Seventy-four patients were recruited in 15 French radiation oncology departments between August 2014 and July 2016. Seven were excluded before treatment because of violation of the inclusion criteria. The intention-to-treat analysis therefore included 67 patients. Half had received prior prostatic irradiation. Median age was 67.7 ± 6.5 years. Grade 2 acute urinary toxicity was observed in 9 of 67 patients (13.4%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Three patients (4.4%) had grade 3 urinary toxicity. Grade 2 acute digestive toxicity was observed in 10 of 67 patients (14.9%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Patients with prior prostate bed irradiation did not exhibit increased urinary or digestive toxicity. The European Organisation for Research and Treatment of Cancer questionnaire scores at 1 year did not worsen significantly. CONCLUSIONS: The acute and 1-year toxicity of the BLINDED protocol was satisfactory, even in patients with a history of prostatic irradiation.

RESUMEN

INTRODUCTION: Whole-gland salvage treatment of radiorecurrent prostate cancer has a high rate of severe toxicity. The standard of care in case of a biochemical recurrence is androgen deprivation treatment, which is associated with morbidity and negative effects on quality of life. A salvage treatment with acceptable toxicity might postpone the start of androgen deprivation treatment, might have a positive influence on the patients' quality of life, and might even be curative. Here, toxicity and biochemical outcome are described after magnetic resonance imaging-guided focal salvage high-dose-rate brachytherapy in patients with radiorecurrent prostate cancer. MATERIALS AND METHODS: Seventeen patients with pathologically proven locally recurrent prostate cancer were treated with focal high-dose-rate brachytherapy in a single 19-Gy fraction using magnetic resonance imaging for treatment guidance. Primary radiotherapy consisted of external beam radiotherapy or low-dose-rate brachytherapy. Tumors were delineated with Ga-68-prostate-specific membrane antigen or F18-choline positron emission tomography in combination with multiparametric magnetic resonance imaging. All patients had a prostate-specific antigen level of less than 10 ng/mL at the time of recurrence and a prostate-specific antigen doubling time of ≥12 months. Toxicity was measured by using the Common Terminology Criteria for Adverse Events version 4. RESULTS: Eight of 17 patients had follow-up interval of at least 1 year. At a median follow-up interval of 10 months (range 3-40 months), 1 patient experienced a biochemical recurrence according to the Phoenix criteria, and prostate-specific membrane antigen testing revealed that this was due to a distant nodal metastasis. One patient had a grade 3 urethral stricture at 2 years after treatment. CONCLUSION: Focal salvage high-dose-rate brachytherapy in patients with radiorecurrent prostate cancer showed grade 3 toxicity in 1 of 17 patients and a distant nodal metastasis in another patient. Whether this treatment option leads to cure in a subset of patients or whether it can successfully postpone androgen deprivation treatment needs further investigation.

RESUMEN

BACKGROUND: Outcome and toxicity profiles of salvage stereotactic ablative radiation strategies for recurrent pre-irradiated brain metastases are poorly defined. This study compared risk-benefit profiles of upfront and salvage iodine-125 brachytherapy (SBT) for small brain metastases. As the applied SBT treatment algorithm required histologic proof of metastatic brain disease in all patients, we additionally aimed to elucidate the value of biopsy before SBT. PATIENTS AND METHODS: Patients with small untreated (n = 20) or pre-irradiated (n =28) suspected metastases intended for upfront or salvage SBT, respectively, were consecutively included. Temporary iodine-125 implants were used (median reference dose: 50 Gy, median dose rate: 15 cGy/h). Cumulative biologically effective doses (BED) were calculated and used for risk assessment. Treatment toxicity was classified according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) criteria. RESULTS: Upfront SBT was initiated in 20 patients and salvage SBT in 23. In 5 patients, salvage SBT was withheld because of proven radiation-induced lesions. Treatment groups exhibited similar epidemiologic data except for tumor size (which was slightly smaller in the salvage group). One-year local/distant tumor control rates after upfront and salvage SBT were similar (94 %/65 % vs. 87 %/57 %, p = 0.45, respectively). Grade I/II toxicity was suffered by 2 patients after salvage SBT (cumulative BED: 192.1 Gy3 and 249.6 Gy3). No toxicity-related risk factors were identified. CONCLUSION: SBT combines diagnostic yield with effective treatment in selected patients. The low toxicity rate in the salvage group points to protective radiobiologic characteristics of continuous low-dose rate irradiation. Upfront and salvage SBT are similarly effective and safe. Histologic reevaluation should be reconsidered after previous radiotherapy to avoid under- or overtreatment.

RESUMEN

PURPOSE: To retrospectively review data of a cohort of patients with biochemical progression after radical prostatectomy, treated according to a uniform institutional treatment policy, to evaluate toxicity and feasibility of high-dose salvage radiation therapy (80 Gy). METHODS AND MATERIALS: Data on 60 patients with biochemical progression after radical prostatectomy between January 2009 and September 2011 were reviewed. The median value of prostate-specific antigen before radiation therapy was 0.9 ng/mL. All patients at time of diagnosis of biochemical recurrence underwent dynamic (18)F-choline positron emission tomography/computed tomography (PET/CT), which revealed in all cases a local recurrence. High-dose salvage radiation therapy was delivered up to total dose of 80 Gy to 18F-choline PET/CT-positive area. Toxicity was recorded according to the Common Terminology Criteria for Adverse Events, version 3.0, scale. RESULTS: Treatment was generally well tolerated: 54 patients (90%) completed salvage radiation therapy without any interruption. Gastrointestinal grade ≥2 acute toxicity was recorded in 6 patients (10%), whereas no patient experienced a grade ≥2 genitourinary toxicity. No grade 4 acute toxicity events were recorded. Only 1 patient (1.7%) experienced a grade 2 gastrointestinal late toxicity. With a mean follow-up of 31.2 months, 46 of 60 patients (76.6%) were free of recurrence. The 3-year biochemical progression-free survival rate was 72.5%. CONCLUSIONS: At early follow-up, (18)F-choline PET/CT-driven high-dose salvage radiation therapy seems to be feasible and well tolerated, with a low rate of toxicity.

RESUMEN

BACKGROUND: Triple therapy with a proton pump inhibitor, moxifloxacin, and amoxicillin has been proven effective in first-line treatment of Helicobacter pylori infection. AIM: To explore 1, the value of triple therapy with esomeprazole, moxifloxacin, and amoxicillin in second-line or rescue treatment of Caucasian patients and 2, the impact of treatment duration on eradication success. METHODS: H. pylori-infected patients with at least one previous treatment failure were randomized to oral esomeprazole 20 mg b.i.d., moxifloxacin 400 mg o.d., and amoxicillin 1000 mg b.i.d. for either 7 (EMA-7) or 14 days (EMA-14). Eradication was confirmed by 13C urea breath test. Antimicrobial susceptibility testing was performed in all patients at baseline and in patients who failed treatment. RESULTS: Eighty patients were randomized, and 60% had ≥ 2 previous treatment failures. Pretreatment resistance against clarithromycin and metronidazole was found in 70.5 and 61.5% of cases, respectively. The intention-to-treat eradication rate was significantly higher after EMA-14 compared with EMA-7 (95.0 vs 78.9%, p = .036). No independent risk factor for treatment failure could be identified. There were no serious adverse events. Five of the EMA-14 patients (12.5%) compared with none of the EMA-7 patients discontinued prematurely because of adverse events (p = .031). Post-treatment resistance against moxifloxacin was found in one of seven patients with isolated organisms (14.3%). CONCLUSION: Second-line/rescue H. pylori eradication therapy with esomeprazole, moxifloxacin, and amoxicillin is very effective and well tolerated. Fourteen days of treatment significantly increase the eradication rate but also the rate of adverse events.

RESUMEN

BACKGROUND: Circadian rhythm disruption was linked to high serum levels of Transforming Growth Factor Receptor α, an Epidermal Growth Factor Receptor (EGFR) ligand and poor survival in patients with metastatic colorectal cancer (mCRC). We hypothesized that EGFR blockade with cetuximab would enhance the activity of chronotherapy as a result of improved circadian coordination. METHODS: All the patients with mCRC referred to our unit for progression on prior chemotherapy over a 30-month-period received weekly cetuximab and fortnightly chronotherapy. RESULTS: Fifty-six patients were treated with a median of six courses of fluoropyrimidine-based chemotherapy and irinotecan (61%), oxaliplatin (25%) or both (14%) after a median of three prior regimens. We found no EFGR amplification by FISH in the tumor of 27 consecutive patients. Acneiform rash and diarrhea were the most common toxicities. Objective response rate was 32.1% and positively correlated with rash grade (p = 0.025). None of the responders had K-Ras mutation in their tumor. Median progression-free and overall survival were 4.6 and 13.7 months, respectively. Complete macroscopic resections of metastases in liver, lung or other abdominopelvic sites were performed following tumor downstaging by the treatment regimen in 11 patients (21%), 8 of whom being alive at 3 years. These figures are twice as high as those reported for first-line combination of cetuximab with conventional chemotherapy or for third line chronotherapy. CONCLUSIONS: The addition of cetuximab to chronotherapy allowed safe and effective therapeutic control of metastases, including their complete resection, despite previous failure of several treatment regimens.

RESUMEN

The objective of this study was to report on technical incidents and early and late complications occurring in high-intensity focused ultrasound (HIFU) treatment of patients with localized prostate cancer. We performed a retrospective review of patients who were treated by Ablatherm at our centre. We recorded all technical incidents, treatment discontinuations and early (<1 month) and late complications. A total of 74 HIFU procedures were performed in 65 patients (55 first-line HIFU treatments and 10 cases of salvage therapy after radiotherapy) over a 5-year period. Median follow-up was 41 months (10-64 months). All the procedures were well tolerated and no intra- or peri-operative deaths occurred. Six technical incidents in the overall population (8.1%) led to discontinuation of the procedure. The early complication rate in patients undergoing first-line HIFU was 36.4%: urinary retention (20%), dysuria (5.4%), urinary infection (3.6%), haematuria (3.6%) and urethral stenosis (3.6%). The late complication rate was 12.7%: urethral stenosis (9%) and dysuria (3.6%). There were no cases of rectourethral fistula. The long-term urinary incontinence rate was 20% and the de novo erectile dysfunction rate was 77.1%. Nine complications (16.4%) required surgical management. The overall complication rate was 49%. Ablatherm is a reliable technique with a relatively high complication rate. However, most complications were minor and required surgical management in a few cases only. Our results confirm that all patients who are offered HIFU treatment should be properly informed of the risks, in particular with regard to continence and sexual function.

RESUMEN

BACKGROUND: Gemcitabine- and 5-fluorouracil (5-FU)- based chemotherapy is a commonly used adjuvant or palliative treatment for patients with pancreatic cancer. However, a standard chemotherapy regimen has yet to be developed for patients refractory to gemcitabine and 5-FU treatment. We attempted to evaluate the efficacy and safety of a combination of irinotecan and oxaliplatin (IROX) as a salvage treatment for patients with gemcitabine- and 5-FU- refractory pancreatic cancer. PATIENTS AND METHODS: Patients with advanced pancreatic cancer who were refractory to prior gemcitabine- and 5-FU- based chemotherapy were enrolled in this study. IROX chemotherapy was administered as follows: Irinotecan, 150 mg/m(2) on day 1; and oxaliplatin, 85 mg/m(2) on day 1 over 90 min every 2 weeks. RESULT: From Mar. 2006 to Dec. 2008, a total of 14 patients were administered 50 cycles of chemotherapy. The male-to-female ratio of the patient group was 11:3. These patients ranged in age from 48 to 73 years (median 65.5 years old). 3 patients (21.4%) evidenced partial responses. four patients (28.6%) exhibited stable disease. The median time to progression and overall survival time were 1.4 (95% CI: 1.2-1.6) months and 4.1 (95% CI: 2.0-6.2) months, respectively. Major hematologic toxicities included grade 1-2 anemia (88%), neutropenia (36%), thrombocytopenia (30%), and grade 3-4 neutropenia (10%). The most frequently detected non-hematological toxicities were grade 3 diarrheas (14%). CONCLUSION: The IROX regimen appears to constitute a feasible and tolerable salvage therapy in patients with advanced pancreatic cancer who have been previously treated with gemcitabine- and 5-FU-based chemotherapy.

RESUMEN

Agents targeting vascular endothelial growth factor (VEGF) signaling have been advocated as frontline therapy for advanced renal cancer. The role of interleukin 2 (IL-2) therapy after resistance to VEGF-targeted therapy remains unexplored. We conducted a retrospective analysis of the tolerability and efficacy of IL-2 therapy in patients who had previously received VEGF-targeted therapy. Twenty-three consecutive patients who received salvage IL-2 therapy were analyzed. Fifteen patients had received prior tyrosine kinase inhibitors (TKIs) (sorafenib or sunitinib), whereas 8 patients had received bevacizumab alone. Six of 23 patients did not receive week 2 of cycle 1 of treatment. All 6 of these patients had received prior TKIs. The incidence of severe cardiac toxicities, including 1 sudden cardiac death, in patients receiving prior TKI was 40% (95% confidence interval, 16.3-67.7%), significantly higher than what is expected from historical experience. Only 1 of 23 patients proceeded to receive a second cycle of IL-2. No patients achieved a partial or complete response to therapy. This retrospective analysis highlights unexpected and severe cardiac toxicities in patients receiving IL-2 after VEGF-targeted TKI therapy. The assumption that IL-2 therapy can be safely administered after TKI therapy may not be valid. Further examination of the safety of this sequential approach is necessary and more cautious patient selection seems warranted.

RESUMEN

OBJECTIVE: To report on the high rectal fistula rate associated with salvage high-intensity focused ultrasound (HIFU) after the failure of combined brachytherapy and external beam radiotherapy (EBRT) for prostate cancer; salvage ablative therapy for prostate cancer is indicated when there is local recurrence after RT, brachytherapy or their combination. PATIENTS AND METHODS: We retrospectively reviewed all men with prostate cancer treated with HIFU between 1 March 2005 and 31 May 2007, and identified five men treated after the failure of both brachytherapy and EBRT for localized prostate cancer. RESULTS: Three of the five men had iodine-seed implantation brachytherapy combined with EBRT as primary treatment, one had high-dose rate brachytherapy combined with EBRT and one had salvage iodine-seed brachytherapy for failed EBRT. Three of the five patients developed a recto-urethral fistula after HIFU. CONCLUSIONS: The high rate of recto-urethral fistula formation in this group might reflect an impaired blood supply or HIFU-associated near-field heating of the rectal wall. Tissue viability and healing might affect this group regardless of the salvage method. Careful patient selection and avoidance of rectal diagnostic biopsies might minimize the risk. Emerging ablative therapies regarded as less invasive than traditional therapies must be used with caution.

RESUMEN

We previously reported that monotherapy with carbapenem or cefepime exhibited efficacy equivalent to cefepime plus an aminoglycoside as initial therapy for febrile neutropenia (FN), achieving an adequate response in two-thirds of the patients. However, only one-third of the remaining poor responders to monotherapy became afebrile after an aminoglycoside was added to the initial carbapenem or cefepime. The present study was designed to evaluate the benefit of intravenous ciprofloxacin for neutropenic patients with fever who were refractory to initial therapy given for the first 3 days. Patients with FN--as defined by an axillary temperature >or=37.5 degrees C and a neutrophil count <1,000/microL-who had no response to initial therapy with carbapenem or cefepime for 72 hours were to receive additional ciprofloxacin 600 mg/day. They were otherwise managed according to the Japanese guidelines for FN. An adequate response was defined as a decline of temperature to <37.5 degrees C within 7 days after initiation of ciprofloxacin treatment. Thirty-one patients with FN (seventeen male and fourteen female; mean age 53.1 +/- 14.8 years) were entered in the study. The initial antibiotics were cefepime (2 - 4 g/day) in twenty and carbapenem (1 - 2 g/day) in eleven. Three patients were excluded from analysis, leaving 28 patients for evaluation of efficacy. The response rate was 16/31 patients (51.6%),with four patients judged non-assessable due to adverse effects, protocol violation or early change to other agents. Adverse events occurred in seventeen patients, but all were mild and reversible. Only three patients had adverse events (skin rash, hepatic dysfunction and elevation of alkaline phosphatase in one patient, respectively) considered related to ciprofloxacin. These findings indicate that addition of intravenous ciprofloxacin is effective against FN refractory to initial antibiotic therapy and has acceptable toxicity.

RESUMEN

OBJECTIVE: To investigate the acute and late toxicities associated with the use of chemoradiation therapy (CRT) with 5-fluorouracil (5-FU) and mitomycin C or mitomycin C alone for primary, adjuvant, and salvage therapy for vulvar cancer. METHODS: Medical charts of 17 patients who received CRT with this regimen were reviewed. Toxicity was scored by 1998 standardized common toxicity criteria, Version 2.0, for acute toxicity and the RTOG/EORT Late Radiation Morbidity Scoring Schema for late toxicity. Median follow-up was 20 months (range: 5-74 months). RESULTS: Six patients had grade 4 neutropenia. In three patients, life-threatening neutropenic sepsis developed after the second cycle of chemotherapy. Severe enterocolitis was a direct cause of death in two patients. In four patients, the second cycle of chemotherapy was cancelled because of severe toxicity associated with the first cycle. One patient had grade 4 skin toxicity in the vulvar-perineal area. Six patients had grade 3 and seven patients had grade 2 acute skin toxicity. Skin toxicity necessitated the interruption of CRT in nine patients at a median dose of 32.4 Gy (range: 16.2-48 Gy). One patient developed bowel perforation and colovaginal fistula 1.5 years after completion of CRT. CONCLUSION: Chemoradiation therapy utilizing 5-FU and mitomycin C or mitomycin C alone in the treatment of vulvar cancer can be associated with a high incidence of morbidity and mortality. Strict attention to indications for treatment interruptions or chemotherapy dose adjustments is obligatory for safe delivery of CRT to these patients.

RESUMEN

Thalidomide is active both as single agent and in combination-therapy against refractory or relapsing multiple myeloma. Eigth patients previously treated were given Thalidomide 100mg/daily plus Dexametasone 40mg/daily for four days each month (Thali-Dexa) and followed for response, prognostic factors and side effects. Two patients had early death (one from massive cerebral ischemic stroke, the other from dementia and progressive renal failure), one patient progressed during Thali-Dexa (thalidomide 200mg) and was rescued with chemotherapy, two patients required increasing thalidomide dosage (to 200 and 400mg, respectively) because of progressive disease, three patients had stable disease remission lasting from 4m+ to 16m+. Thali-Dexa is a useful agent but age and vascular/metabolic diseases may increase the risk of severe side effects. Early decrease in erythrocyte sedimentation rate seems to correlate with better disease control.
