Optimal combination of radiofrequency ablation with chemoradiotherapy for locally advanced pancreatic cancer

Problems have been reported in the treatment of pancreatic cancer with radiofrequency ablation (RFA), such as the friability of the organ itself. This report presents possible solutions to such problems. Although our patient suffered from locally advanced unresectable pancreatic cancer, she remained well at 18 mo after RFA with no evidence of recurrence. To ameliorate the side effects of RFA, after a palliative bypass procedure, the subject was treated with combined radiotherapy and chemotherapy. After this regimen had been administered, a contrast-enhanced computed tomography scan confirmed that RFA is a viable approach to the treatment of pancreatic cancer as the chemoradiotherapy had resulted in marked tumor shrinkage and pancreatic fibrosis; i.e., sufficient tumor ablation was achieved without serious RFA-related complications, such as pancreatitis or pancreatic fistulae. The present case suggests that RFA combined with preceding chemoradiotherapy is safe and effective for the palliative treatment of locally advanced pancreatic cancer.     

Two-year survivor in response to gemcitabine-based chemotherapy for advanced pancreatic cancer with multiple lung metastases

A 65-year-old woman was admitted to our hospital for appetite loss and jaundice. Abdominal CT scan and ultrasonography both revealed a tumor in the head of the pancreas. Chest CT scan showed multiple nodules in both lungs. The patient was diagnosed as having advanced pancreatic cancer with multiple lung metastases. The primary tumor showed a partial response to the administration of gemcitabine 1,000 mg/m2 on days 1, 8 and 15 of a 28-day cycle. Concurrent treatment with 5-fluorouracil (200 mg/day) was efficacious against the lung metastases. One year later the pancreatic and lung tumors had enlarged, and cisplatin (20 mg/body) was added to the protocol. For 20 months the patient was treated as an outpatient, maintaining good quality of life. The patient died of progressive disease 25 months after her first hospital admission.

Fractionated stereotactic body radiation therapy in the treatment of primary, recurrent, and metastatic lung tumors: the role of positron emission tomography/computed tomography-based treatment planning

PURPOSE: The aim of this study was to assess the outcomes of patients treated with stereotactic body radiation therapy (SBRT) in patients with primary, recurrent, or metastatic lung lesions, with a focus on positron emission tomography (PET)/computed tomography (CT)-based management. PATIENTS AND METHODS: Fifty-one patients with primary stage I non-small-cell lung cancer (NSCLC; n = 26), recurrent lung cancer after definitive treatment (n = 12), or solitary lung metastases (n = 13) were treated with SBRT between 2005 and 2007. Patients were treated with the CyberKnife Robotic Radiosurgery System with Synchrony respiratory tracking. A dose of 60 Gy was delivered in 3 fractions. All patients had CT or PET/CT performed at approximately 3-month intervals after treatment. RESULTS: The median follow-up was 12 months. Local control at median follow-up was 85% in patients with stage I NSCLC, 92% in patients with recurrent lung cancer, and 62% in the patients with solitary lung metastasis. Analysis of the 28 patients with pre- and post-treatment PET/CT scans demonstrated that those with stable disease (n = 4) had a mean standardized uptake value (SUV) decrease of 28%, partial responders (n = 11) had a decrease of 48%, and patients with a complete response (n = 11) had a decrease of 94%. Patients with progressive disease (n = 2) had an SUV decrease of only 0.4%. Only 2 patients (7%) who had reduced fluorodeoxyglucose avidity later progressed locally. No correlations were found between pretreatment SUV and tumor response, disease progression, or survival. Overall 1-year survival rates were 81%, 67%, and 85% among the patients with primary NSCLC, recurrent lung cancer, and solitary lung metastases, respectively. CONCLUSION: Stereotactic body radiation therapy with CyberKnife is an effective treatment for patients with medically inoperable recurrent or metastatic lung cancer. Positron emission tomography/CT is valuable in staging, planning, and evaluating treatment response and might predict long-term outcome.

Prolonged survival of a woman with lung cancer diagnosed and treated with chemotherapy during pregnancy. Review of cases reported

Lung cancer is the most common cause of cancer death in women in the US, diagnosis during pregnancy is rare and has been reported 34 times. We report a case of a 34-year-old woman with stage III locally advanced lung cancer diagnosed during the 27th week of pregnancy. Chest X-ray and thorax MRI revealed a 9 cm × 7 cm mass in the upper right lung lobe. CT guided FNA biopsy indicated adenocarcinoma. Neoadjuvant chemotherapy was administered with vinorelvine (Navelbine^®) and cisplatin for three cycles with partial response. At 39 weeks, she delivered a healthy baby. Right upper lobectomy with complete lymphadenectomy was performed 3 weeks later. Final pathology was reported as an adenocarcinoma of 7.5 cm × 6.2 cm with involvement of 16/30 lymph nodes. She received three additional cycles of chemotherapy and radiotherapy. Follow-up with CT scan after 11 months did not show recurrence.
