Preoperative intensified radiochemotherapy for rectal cancer: experience of a single institution.

PURPOSE: The aim of our study was to evaluate the feasibility and the effectiveness of an intensified neoadjuvant protocol with the addition of weekly oxaliplatin in the preoperative strategy of rectal cancer treatment. PATIENTS AND METHODS: Patients with locally advanced rectal cancer received continous infusion 5-Fluorouracil (5-FU) 200 mg/m(2)/day in combination with weekly oxaliplatin at a dose of 50 mg/m(2). Doses of radiotherapy were 45 Gy to the whole pelvis plus 5.4-9 Gy to the tumour mass. The primary end-points of the study were evaluation of toxicity, compliance with radiotherapy and chemotherapy, downstaging, pathological complete response (pCR) and the rate of sphincter preservation for distal cancers. Secondary end-points were relapse-free and overall survival. RESULTS: From November 2006 to June 2009, 51 patients were enrolled into the study. Compliance with chemotherapy was 80%. The incidence of G3 diarrhoea and proctitis were 17.6% and 21.5%, respectively. Surgery was performed in 48 patients with 100% R0 resection. 76.4% of low-lying tumours underwent conservative treatment. Seventy-nine percent of patients were downstaged: T and N downstaging were observed in 71% and 75% of patients, respectively. A pCR was obtained in 11 (22.9%) patients. CONCLUSIONS: Intensification of neoadjuvant treatment for rectal cancer with the addition of weekly oxaliplatin is feasible, with remarkable rates of downstaging and pathological complete response. Data on sphincter preservation for distal cancers were excellent. Phase III trials with a longer follow-up will establish whether this good outcome in terms of surrogate end-points will translate into better rates of disease-free and overall survival.

Comparison between intensified neoadjuvant treatment and standard preoperative chemoradiation for rectal cancer.

OBJECTIVES: The aim of the current study was to compare a neoadjuvant regimen containing oxaliplatin with standard preoperative treatment for rectal cancer. METHODS: From December 2006 to December 2007, 20 patients with rectal cancer were treated at our Institution with the weekly addition of oxaliplatin (50 mg/m(2)) to radiotherapy (50.4-54.0 Gy in 28-30 daily fractions) and continuous infusion of 5-fluorouracil (200 mg/m(2)). The results of the regimen were compared with a historical control group including 21 consecutive patients previously treated with standard 5-fluorouracil treatment from December 2004 to October 2006. RESULTS: Both the rate of sphincter preservation in low rectal cancer (91.7% vs 36.4%, P = 0.009) and the rate of downstaging (84.2% vs 47.6%, P = 0.023) were higher in the oxaliplatin group than in the control group. Pathological complete response was achieved in 8 patients (42.1%) in the oxaliplatin group and in 4 patients (19.0%) in the control group (P = 0.172). When ypT0-pT1 stages were analyzed together, the P value was 0.051. Acute toxicity was increased in the oxaliplatin group, with a higher incidence of G3 diarrhea and pelvic pain than in the control group (30.0% vs 14.3%, P = NS). CONCLUSIONS: Our data seem to correlate the addition of oxaliplatin to the standard treatment for rectal cancer with higher rates of sphincter preservation, down-staging and complete response. Toxicity is increased and requires careful monitoring. However, our results refer to a retrospective comparison of a small series of patients and need to be validated by the large, phase III randomized trial currently ongoing.

Radiotherapy and chemotherapy in the conservative treatment of anal canal carcinoma.

AIM: To evaluate the feasibility of conformal radiotherapy and concurrent chemotherapy in patients with anal canal carcinoma. PATIENTS AND METHODS: Between 1990 and 2006, 83 patients affected by anal canal carcinoma were treated at the Radiotherapy Department of "La Sapienza" University of Rome. In all patients, a daily dose of 1.8 Gy, five times per week, was given for a total dose of 45 Gy for the whole pelvis (CTV1) and of 55-60 Gy for the tumor bed (CTV2). In 63 patients, chemotherapy consisted of two cycles of 5-fluorouracil (5-FU) and mitomycinC (MMC) or cisplatin delivery during the first and last week of radiotherapy. RESULTS: The median follow-up time for all patients was 56.2 months. Treatment response was considered complete in 53 patients (63.8%) and partial in 30 patients (36.1%). Local tumor relapse was observed in 13 patients (15.6%). The probability of overall survival for all patients at 5 years was 75%: 39% in patients who underwent radiotherapy alone and 85% in patients who underwent radiochemotherapy (p=0.0013). Concerning acute toxicity, 9 patients developed grade 1 skin toxicity (10.8%), 35 grade 2 (42.1%), 26 grade 3 (31.3%) and 3 grade 4 (3.6%); eleven patients had grade 2 diarrhea (14.5%) and 2 grade 3 diarrhea (2.4%). CONCLUSION: This analysis suggests that the treatment scheme employed was effective for anal sphincter preservation and local control.

Carcinoma of the vulva: clinical results of exclusive and adjuvant radiotherapy.

BACKGROUND: The aim of this study was to evaluate the historical cohort of 61 patients with carcinoma of the vulva, treated with radiation therapy from 1986 to 1997. PATIENTS AND METHODS: Twenty-seven patients were submitted to radiation therapy alone and 34 received radiotherapy post limited surgery in early stages and post radical vulvectomy in advanced stages. The dose range varied from 59 to 63 Gy in post-operative patients and 65 Gy to 71 Gy in curative patients. RESULTS: Five-year Overall Survival (OS) and Disease-Free Survival (DFS) for patients treated with irradiation alone and for those treated with post-operative radiotherapy were 50.8% and 69.7%, respectively, without significant statistical difference. For OS multivariate analysis showed statistical difference for stage and age variables, and for stage variable in the case of DFS. CONCLUSION: In early stage vulvar cancer patients OS and DFS are good, with high control rate and low incidence of adverse effect. In loco-regionally-advanced patients, especially in those with stage IV or with > 2 positive lymph nodes, the outcomes are poor.

Texture analysis as imaging biomarker of tumoral response to neoadjuvant chemoradiotherapy in rectal cancer patients studied with 3-T magnetic resonance.

OBJECTIVE: The aim of this study was to determine whether texture features of rectal cancer on T2-weighted (T2w) magnetic resonance images can predict tumoral response in patients treated with neoadjuvant chemoradiotherapy (CRT). MATERIALS AND METHODS: We prospectively enrolled 15 consecutive patients (6 women, 63.2 ± 13.4 years) with rectal cancer, who underwent pretreatment and midtreatment 3-T magnetic resonance imaging. Treatment protocol consisted of neoadjuvant CRT with oxaliplatin and 5-fluorouracile. Texture analysis using a filtration-histogram technique was performed using a commercial research software algorithm (TexRAD Ltd, Somerset, England, United Kingdom) on unenhanced axial T2w images by manually delineating a region of interest around the tumor outline for the largest cross-sectional area. The technique selectively filters and extracts textures at different anatomic scales followed by quantification of the histogram using kurtosis, entropy, skewness, and mean value of positive pixels. After CRT, all patients underwent complete surgical resection and the surgical specimen served as the gold standard. RESULTS: Six patients showed pathological complete response (pCR), and 4 patients, partial response (PR). Five patients were classified as nonresponders (NRs). Pretreatment medium texture-scale quantified as kurtosis was significantly lower in the pCR subgroup in comparison with the PR + NR subgroup (P = 0.01). Midtreatment kurtosis without filtration was significantly higher in pCR in comparison with PR + NR (P = 0.045). The change in kurtosis between midtreatment and pretreatment images was significantly lower in the PR + NR subgroup compared with the pCR subgroup (P = 0.038). Pretreatment area under the receiver operating characteristic curves, to discriminate between pCR and PR + NR, was significantly higher for kurtosis (0.907, P < 0.001) compared with all other parameters. The optimal cutoff value for pretreatment kurtosis was 0.19 or less. Using this value, the sensitivity and specificity for pCR prediction were 100% and 77.8%, respectively. CONCLUSION: Texture parameters derived from T2w images of rectal cancer have the potential to act as imaging biomarkers of tumoral response to neoadjuvant CRT.

Radiotherapy alone and chemoirradiation in recurrent squamous cell carcinoma of the vulva.

AIM: To evaluate the role of radiotherapy alone or combined with chemotherapy in the treatment of recurrent vulvar cancer, emphasising the prognostic factors and outcomes. MATERIALS AND METHODS: Twenty women with loco-regional recurrence of vulvar carcinoma were retrospectively reviewed. Eleven patients were managed with a combination of chemotherapy and radiotherapy, seven out of these with concomitant radio-chemotherapy and four with neo-adjuvant chemotherapy. Nine patients were submitted to radiotherapy alone. The total dose of radiation therapy ranged from 30 Gy to 70 Gy. RESULTS: The median follow-up was 6 months (range 2-70 months). The 5-year overall and disease-free survival for the entire cohort was 20%. The outcomes included 6 complete response (CR), 10 partial response (PR) and 4 no change (NC). Patients with one site of recurrence and size of lesion < or = 3 cm were long survivors and disease-free at 5 years; all these women received a total dose of radiation therapy > or = 6480 cGy. CONCLUSION: We emphasize the importance of the number, site and diameter of recurrences as prognostic indicators; the outcomes of these patients were also affected by the total dose of radiation therapy.

Radiotherapy in the treatment of stage III-IV hypopharyngeal carcinoma.

BACKGROUND: The aim of this study was to evaluate the role of radiation therapy alone, employing standard fractionation, in stage III-IV hypopharyngeal carcinoma. MATERIALS AND METHODS: Fourteen (38.9%) stage III and 22 (61.1%) stage IV patients with hypopharyngeal carcinoma were submitted, with curative intent, to exclusive radiotherapy to the primary tumor and regional draining lymph nodes, level II, III, IV, V and VI. Total dose ranged from 68 to 72 Gy. RESULTS: The 5-year overall survival (OS) and disease-specific survival (DSS) rates were 15.6% and 28.1%, respectively. Five-year OS in stage III and IV patients was, respectively, 33% and 5% (p=0.028) and DSS was, respectively, 50% and 16% (p=0.029). Five-year OS and DSS rate in N0 versus N+ patients were respectively 37.5% and 75% versus 8.3% and 12.5% (p=0.07 and p=0.05). CONCLUSION: Overall survival at 5 years for III-IV hypopharyngeal tumor treated with radiotherapy alone is poor. It is possible that the addition of the best radiation fractionation to the best concurrent chemotherapy may improve the results, with acceptable toxicity.

Transrectal ultrasound color Doppler in the evaluation of recurrence of anal canal cancer.

OBJECTIVE: aim was to obtain elements for a differential diagnosis between post-radiation fibrosis and residual tumor or local relapse in anal canal cancer through detection of presence/absence of intralesional blood flow. Transrectal ultrasound and color Doppler were compared. METHODS: 43 patients underwent transrectal ultrasound sonography and color Doppler before and after therapy to assess intralesional blood flow and flow pattern (spotty and linear signals). All diagnostic imaging results were compared to histological analysis. Specificity was submitted to statistical analysis using McNemar test. RESULTS: before therapy 34 lesions (79%) showed color signal; no signal in 9 (21%), which were excluded from our analysis. Eighteen of the 34 patients considered, presented complete response to therapy, 14 partial response and two no response. After therapy, signal disappeared in 17 patients (94%); one false-positive (6%) presented spotty signals; 16 of 34 patients presented changed color signal. Color Doppler showed higher specificity than grey scale transrectal ultrasound in the differentiation of fibrosis from tumor. Response was confirmed by histological examination, considered gold standard. McNemar test demonstrated the significance of color Doppler (P < 0.0001). CONCLUSION: color Doppler considerably increases transrectal ultrasound specificity in differentiating tumor relapse from fibrosis in anal canal cancer.

Management of persistent anal canal carcinoma after combined-modality therapy: a clinical review.

Anal canal carcinoma is a rare gastro-intestinal cancer. Radiochemotherapy is the recommended primary treatment for patients with non-metastatic carcinoma; surgery is generally reserved for persistent or recurrent disease. Follow-up and surveillance after primary treatment is paramount to classify patients in those with complete remission, persistent or progressive disease. Locally persistent disease represents a clinically significant problem and its management remains subject of some controversy.The aim of this systematic review is to summarise recommendations for the primary treatment of anal canal carcinoma, to focus on the optimal time to consider residual disease as genuine persistence to proceed with salvage treatment, and to discern how this analysis might inform future clinical trials in management in this class of patients.

Relationship of clinical and pathologic nodal staging in locally advanced breast cancer: current controversies in daily practice?

Systemic neo-adjuvant therapy plays a primary role in the management of locally advanced breast cancer. Without having any negative effect in overall survival, induction chemotherapy potentially assures a surgery approach in unresectable disease or a conservative treatment in technically resectable disease and acts on a well-vascularized tumor bed, without the modifications induced by surgery. A specific issue has a central function in the neo-adjuvant setting: lymph nodes status. It still represents one of the strongest predictors of long-term prognosis in breast cancer. The discussion of regional radiation therapy should be a matter of debate, especially in a pathological complete response. Currently, the indication for radiotherapy is based on the clinical stage before the surgery, even for the irradiation of the loco-regional lymph nodes. Regardless of pathological down-staging, radiation therapy is accepted as standard adjuvant treatment in locally advanced breast cancer.

Neoadjuvant strategy as initial treatment in resectable pancreatic cancer: concrete evidence of benefit.

Pancreatoduodenectomy remains the recommended treatment in potentially curative strategies for pancreatic carcinoma. Due to high local failure rates even after complete resection, a multi-modality treatment approach is paramount in the management of resectable disease. Despite there being insufficient evidence to recommend a specific neoadjuvant strategy, several studies have tested the use of preoperative chemoradiotherapy in this sub-group of patients, achieving promising results. The treatment is well-tolerated, with higher rates of negative margins and lower rates of lymph node positivity at resection, a decrease in local failure and benefit in overall survival. Considering the poor oncological results after primary surgical treatment, neoadjuvant strategy should be considered as a valid alternative in resectable pancreatic carcinoma.

Two different intensity-modulated radiotherapy strategies for patients with high-risk prostate cancer.

AIM: To compare toxicity profiles of two different intensity-modulated radiation therapy (IMRT) strategies in patients with high-risk prostate cancer. PATIENTS AND METHODS: From May 2010 to September 2012, 43 patients with high-risk prostate cancer were treated with IMRT and concurrent hormone therapy; 23 patients were treated by conventional fractionation (IMRT/C) and 20 patients by simultaneous integrated boost (IMRT/SIB). Acute and late toxicities were compared for each group. RESULTS: Severe acute genitourinary toxicity was recorded in 8.6% and 2% of patients in the IMRT/C and IMRT/SIB group, respectively. Genitourinary toxicity G2 was observed in 39.1% (IMRT/C group) and 25% (IMRT/SIB group) of patients. Severe acute gastrointestinal toxicity was not observed; Grade 2 acute gastrointestinal toxicity was recorded in 21.7% (IMRT/C group) and 10% (IMRT/SIB group). Grade 2 late genitourinary toxicity was observed in 26% (IMRT/C group) and 15% (IMRT/SIB group), whereas G2 late gastrointestinal toxicity in 34.5% and 30% of patients, respectively. No significant differences in incidence and severity of genitourinary and gastrointestinal toxicity were detected between the two IMRT treatment strategies. CONCLUSION: IMRT/SIB was well-tolerated with favorable rates of acute and late toxicity, both genitourinary and gastrointestinal. Compared to IMRT/C, IMRT/SIB maintained the same efficacy and reduced the overall treatment time.

Number of mediastinal lymph nodes as a prognostic factor in PN2 non small cell lung cancer: a single centre experience and review of the literature.

Currently the most important prognostic factor in lung cancer is the stage. In the current lung TNM classification system, N category is defined exclusively by anatomic nodal location though, in other type of tumours, number of lymph nodes is confirmed to be a fundamental prognostic factor. Therefore we evaluated the number of mediastinal lymph nodes as a prognostic factor in locally advanced NSCLC after multimodality treatment, observing a significant effect of the number of lymph nodes in terms of OS (p<0.01) and DFS (p<0.001): patients with a low number of positive mediastinal nodes have a better prognosis.

Multiple bone metastases from glioblastoma multiforme without local brain relapse: a case report and review of the literature.

Extracranial metastases from glioblastoma multiforme (GBM) are a very rare event, even if an increasing incidence has been documented. We report the case of a young woman with primary GBM who developed bone metastases without local brain relapse. Because of persistent headache and visual disturbances, in March 2011 the patient underwent magnetic resonance imaging (MRI) evidencing a temporoparietal mass, which was surgically resected. Histology revealed GBM. She was given concomitant chemoradiotherapy according to the Stupp regimen. After a 4-week break, the patient received 6 cycles of adjuvant temozolomide according to the standard 5-day schedule every 28 days. In December 2011 she complained of progressive low back pain, and MRI showed multiple bone metastases from primary GBM, confirmed by histology. Cases of metastatic GBM in concurrence with a primary brain tumor or local relapse are more common in the literature; only a few cases have been reported where extracranial metastases from GBM occurred without any relapse in the brain. Here we report our experience.

Helical tomotherapy: an innovative radiotherapy technique for the treatment of locally advanced oropharynx and inoperable oral cavity carcinoma.

BACKGROUND: To report our initial clinical experience of helical tomotherapy (HT) in the treatment of locally advanced oropharynx and inoperable oral cavity cancer. METHODS: Between February 2008 and January 2011, 24 consecutive patients, 15 with oropharyngeal cancer and 9 with oral cavity cancer were treated with exclusive radiotherapy or concomitant chemoradiotherapy. Simultaneous integrated boost (SIB) in 30 fractions scheme was prescribed to all patients, using Helical Tomotherapy. Doses administered to primary tumor, oropharynx/oral cavity and positive lymph-nodes and negative lymph-nodes were 66-67.5 Gy, 60-63 Gy and 54 Gy, respectively. RESULTS: Complete response rate for the oropharynx and the oral cavity group was 86.7% and 77.8%, respectively. The 1 and 2-year Overall Survival (OS) and Disease Free Survival (DFS) rate for the oropharynx group was 92.9%, 85.1%, 92.9% and 77.4% respectively. For the oral cavity group, 1 and 2-year OS and DFS rates were 55.6%, 55.6%, 75% and 75%, respectively. No patient developed grade ≥3 mucositis, dysphagia or dermatitis. The maximum late-toxicity grade observed was 2, for all the variables examined. CONCLUSIONS: HT appears to achieve encouraging clinical outcomes in terms of response, survival and toxicity rates.

Neoadjuvant-intensified treatment for rectal cancer: time to change?

AIM: To investigate whether neoadjuvant-intensified radiochemotherapy improved overall and disease-free survival in patients with locally advanced rectal cancer. METHODS: Between January 2007 and December 2011, 80 patients with histologically confirmed rectal adenocarcinoma were enrolled. Tumors were clinically classified as either T3 or T4 and by the N stage based on the presence or absence of positive regional lymph nodes. Patients received intensified combined modality treatment, consisting of neoadjuvant radiation therapy (50.4-54.0 Gy) and infusional chemotherapy (oxaliplatin 50 mg/m(2)) on the first day of each week, plus five daily continuous infusions of fluorouracil (200 mg/m(2) per die) from the first day of radiation therapy until radiotherapy completion. Patients received five or six cycles of oxaliplatin based on performance status, clinical lymph node involvement, and potential risk of a non-sphincter-conserving surgical procedure. Surgery was planned 7 to 9 wk after the end of radiochemotherapy treatment; adjuvant chemotherapy treatment was left to the oncologist's discretion and was recommended in patients with positive lymph nodes. After treatment, all patients were monitored every three months for the first year and every six months for the subsequent years. RESULTS: Of the 80 patients enrolled, 75 patients completed the programmed neoadjuvant radiochemotherapy treatment. All patients received the radiotherapy prescribed total dose; five patients suspended chemotherapy indefinitely because of chemotherapy-related toxicity. At least five cycles of oxaliplatin were administered to 73 patients. Treatment was well tolerated with high compliance and a good level of toxicity. Most of the acute toxic effects observed were classified as grades 1-2. Proctitis grade 2 was the most common symptom (63.75%) and the earliest manifestation of acute toxicity. Acute toxicity grades 3-4 was reported in 30% of patients and grade 3 or 4 diarrhoea reported in just three patients (3.75%). Seventy-seven patients underwent surgery; low anterior resection was performed in 52 patients, Miles' surgery in 11 patients and total mesorectal excision in nine patients. Fifty patients showed tumor downsizing ≥ 50% pathological downstaging in 88.00% of tumors. Out of 75 patients surviving surgery, 67 patients (89.33%) had some form of downstaging after preoperative treatment. A pathological complete response was achieved in 23.75% of patients and a nearly pathologic complete response (stage ypT1ypN0) in six patients. An involvement of the radial margin was never present. During surgery, intra-abdominal metastases were found in only one patient (1.25%). Initially, 45 patients required an abdominoperineal resection due to a tumor distal margin ≤ 5 cm from the anal verge. Of these patients, only seven of them underwent Miles' surgery and sphincter preservation was guaranteed in 84.50% of patients in this subgroup. Fourteen patients received postoperative chemotherapy. In the full analysis of enrolled cohort, eight of the 80 patients died, with seven deaths related to rectal cancer and one to unrelated causes. Local recurrences were observed in seven patients (8.75%) and distant metastases in 17 cases (21.25%). The five-year rate of overall survival rate was 90.91%. Using a median follow-up time of 28.5 mo, the cumulative incidence of local recurrences was 8.75%, and the overall survival and disease-free survival rates were 90.00% and 70.00%, respectively. CONCLUSION: The results of this study suggest oxaliplatin chemotherapy has a beneficial effect on overall survival, likely due to an increase in local tumor control.

Diffusion-weighted magnetic resonance application in response prediction before, during, and after neoadjuvant radiochemotherapy in primary rectal cancer carcinoma.

INTRODUCTION: Our interest was to monitor treatment response using ADC value to predict response of rectal tumour to preoperative radiochemotherapy. MATERIALS AND METHODS: Twenty-two patients were treated with long course of radiochemotherapy, followed by surgery. Patients were examined by diffusion-weighted imaging MRI at three-time points (prior, during, and after radiochemotherapy) and were classified as responders and nonresponders. RESULTS: A statistical significant correlation was found between preradiochemotherapy ADC values and during treatment ADC values, in responders (F = 21.50, P value <0.05). An increase in ADC value during treatment was predictive of at least a partial response. DISCUSSION: Response of tumour to neoadjuvant therapy cannot be easily evaluated, and such capability might be of great importance in clinical practice, because the number of irradiated and operated patients may be superior to the number of who will really benefit from this multimodal treatment. A reliable prediction of the final clinical TN stage would allow radiotherapist to adapt multidisciplinary approach to a less invasive management, sparing surgical procedure in responder patients or even allowing an early surgery in nonresponders, which would significantly reduce radiochemotherapy related toxicity. Conclusion. Early evaluation of response during neoadjuvant radiochemotherapy treatment shows great promise to predict tumour response.

Complete response and long-term survival in malignant pleural mesothelioma: case report.

UNLABELLED: Malignant pleural mesothelioma is a rare tumour. A three-modal strategy, comprising of surgery, radiotherapy and chemotherapy has been shown to be essential for appropriate management. Current literature evidences the importance of radiation therapy in the adjuvant setting for local control of the disease, as part of a multidisciplinary treatment, with increment of progression-free survival rate, but also of disease-free survival. CASE REPORT: At the beginning of 2007, a 26-year-old Peruvian woman was admitted to the hospital referring breathlessness and other non-specific symptoms such as fever and weight loss. After the diagnosis of pleural mesothelioma by thoracoscopic talc insufflation, combined with pleural biopsy, and total body computed tomographic scan, the patient underwent two cycles of neoadjuvant chemotherapy with pemetrexed (500 mg/m(2)) and cisplatin (75 mg/m(2)), followed by an extra-pleural pneumonectomy. After 6 months, the patient was treated with three-dimensional external beam radiation therapy to the left hemithorax. Computed tomographic scans, performed after the ending of the radiotherapy, integrated with positron-emission tomography, were all negative for neoplastic pathology. The patient remains in good health and free from recurrence at four years. CONCLUSION: This clinical case shows a disease-free survival interval of 4 years for malignant pleural mesothelioma. A good staging system and a combined treatment, involving surgery, neoadjuvant chemotherapy and adjuvant radiation therapy, represent a useful strategy not only to contain local disease progression, but even to increase disease-free survival in pleural mesothelioma.

Chemoradiation as definitive treatment for primary squamous cell cancer of the rectum.

In this report, we present a case of advanced squamous cell cancer located in the rectum of a 78-year-old woman treated with chemoradiation with curative intent. The patient showed a complete clinical response to chemoradiation; multiple biopsies were performed at the site of the previous mass 5 mo after the end of treatment and histological examination showed no residual tumour in the specimens. Surgical intervention was avoided and the patient was free of disease 12 mo after the diagnosis of cancer. Primary chemoradiation should be considered as the treatment of choice for this rare malignancy.
