ABSTRACT
We present a rare case of diarrhea and neutropenia caused by Cryptococcus laurentii (C. laurentii) infection in old patient with metastatic rectal cancer who underwent FOLFOX plus Cetuximab chemotherapy. C. laurentii is an extremely rare human pathogen. To the best of our knowledge, here, we report the first case of diarrhea and neutropenia caused by C. laurentii in a 74-year-old man with metastatic rectal cancer and hepatic metastases who underwent FOLFOX plus Cetuximab chemotherapy.
ABSTRACT
INTRODUCTION: Hepatocellular carcinoma (HCC) is one of the most common solid tumors in the world. HCC muscle and cutaneous metastases are rare and can occur by hematogenous spread or following surgical procedures performed for diagnostic or therapeutic aims. CASE STUDY: We present a 47-year-old man underwent liver biopsy followed by surgical resection for moderately differentiated HCC in January 1999. In February 2010 the patient presented with HCC cutaneous metastases in the surgical scare and with HCC metastases of the right abdominal rectus muscle. En bloc tumor resection with the right abdominal rectus muscle was performed. In March 2011 the patient underwent resection of a locoregional muscle relapse. In November 2011 we started Sorafenib for intraepatic recurrence. DISCUSSION: This case suggests that in the follow-up of patients who underwent surgical resection or diagnostic and therapeutic procedures for HCC should be considered the possibility of abdominal wall metastasis even after many years, particularly in the cases with favorable evolution.
ABSTRACT
PURPOSE: To evaluate the feasibility and efficacy of moderately accelerated intensity-modulated radiation therapy (IMRT) along with weekly cisplatin, after induction chemotherapy, in patients with locally advanced unresectable head and neck cancer (HNC). METHODS AND MATERIALS: Patients with Stage III or IV locally advanced HNC, without progressive disease after three courses of induction chemotherapy, received concurrent chemo-IMRT (weekly cisplatin 30 mg/m(2) plus simultaneous integrated boost IMRT). A total of 67.5 Gy in 30 fractions were delivered to primary tumor and involved nodes, 60 Gy in 30 fractions to high-risk nodal areas, and 55.5 Gy in 30 fractions to low-risk nodal areas. RESULTS: In all, 36 patients (median age, 56 years) with International Union Against Cancer (UICC) Stage III (n = 5) and IV (n = 31) were included. Of the 36 patients, 17 had received CF (cisplatin and 5-fluorouracil (CF) and 19 had received docetaxel cisplatin and 5-fluorouracil (DCF). During concurrent chemoradiation, 11 of 36 patients (30.5%) experienced Grade III mucositis (CF, 47%; DCF, 15%; p < 0.04). Grade III pharyngeal-esophageal toxicity was observed in 5 of 19 patients (26.3%; CF, 0.0%; DCF, 26.3%; p = 0.02). Two patients died of complications (5.5%). After chemoradiation, the complete response rate was 63.8%. Two-year local control was 88.7%. Two-year progression free survival and overall survival were 74.5% and 60.9%, respectively. CONCLUSIONS: In our experience, a moderately accelerated chemo-IMRT was feasible after induction chemotherapy. However, a noteworthy early death rate of 5.5% was observed. Intensive supportive care strategies should be defined to better manage radiation-induced toxic effects. Longer follow-up is required to determine the incidence of late radiation toxicities and tumor control rates.

PURPOSE: To determine the maximum tolerated dose (MTD) of fractionated intensity-modulated radiotherapy (IMRT) with temozolomide (TMZ) in patients with glioblastoma. METHODS AND MATERIALS: A Phase I clinical trial was performed. Eligible patients had surgically resected or biopsy-proven glioblastoma. Patients started TMZ (75 mg/day) during IMRT and continued for 1 year (150-200 mg/day, Days 1-5 every 28 days) or until disease progression. Clinical target volume 1 (CTV1) was the tumor bed +/- enhancing lesion with a 10-mm margin; CTV2 was the area of perifocal edema with a 20-mm margin. Planning target volume 1 (PTV1) and PTV2 were defined as the corresponding CTV plus a 5-mm margin. IMRT was delivered in 25 fractions over 5 weeks. Only the dose for PTV1 was escalated (planned dose escalation: 60 Gy, 62.5 Gy, 65 Gy) while maintaining the dose for PTV2 (45 Gy, 1.8 Gy/fraction). Dose limiting toxicities (DLT) were defined as any treatment-related nonhematological adverse effects rated as Grade >or=3 or any hematological toxicity rated as >or=4 by Radiation Therapy Oncology Group (RTOG) criteria. RESULTS: Nineteen consecutive glioblastoma were treated with step-and-shoot IMRT, planned with the inverse approach (dose to the PTV1: 7 patients, 60 Gy; 6 patients, 62.5 Gy; 6 patients, 65 Gy). Five coplanar beams were used to cover at least 95% of the target volume with the 95% isodose line. Median follow-up time was 23 months (range, 8-40 months). No patient experienced DLT. Grade 1-2 treatment-related neurologic and skin toxicity were common (11 and 19 patients, respectively). No Grade >2 late neurologic toxicities were noted. CONCLUSION: Accelerated IMRT to a dose of 65 Gy in 25 fractions is well tolerated with TMZ at a daily dose of 75 mg.
