Standard therapy for advanced head and neck cancer consists of a combination of surgery and radiation. However, survival of this patient population has not improved during the past 20 years. Many different multimodality treatment schedules have been proposed, and chemotherapy is often used with the intent of organ preservation. The present study was intended to establish the efficacy of concomitant chemoradiation with a single agent carboplatin in advanced head and neck cancers.The objectives were to investigate the feasibility of concomitant administration of carboplatin, monitor acute toxicity during radiotherapy, and determine subacute side effects, such as wound healing following surgery after chemoradiotherapy. A prospective study was conducted wherein a total of 40 patients with stage III and IV squamous cell carcinomas of oral cavity, oropharynx, hypopharynx and larynx were enrolled. All patients were treated with external beam radiotherapy and weekly carboplatin area under curve (AUC of 5). Radiotherapy was given in single daily fractions of 1.8-2 grays (Gy) to a total dose of 66-72 Gy. Salvage surgery was performed for any residual or recurrent locoregional disease. Neck dissection was recommended for all patients with neck disease showing less than a complete response after chemoradiation. A total of 40 patients were enrolled of whom 32 were males and 8 were females. Highest incidence of cancer was seen in the 5th-6th decades of life with a median age of 47.7 years. Oropharyngeal tumours constituted a maximum of 21 patients followed by hypopharynx in 10, larynx in 7 and oral cavity in 2. 80% of the patients had a neck node on presentation of which 40% had N2-N3 nodal status. TNM staging revealed that 58% of patients were in stage III and 43% in stage IV. Evaluation of acute toxicity revealed that 50% had grade II mucositis, 25% grade III mucositis, 2.5% grade IV mucositis. 50% of patients had grade I skin reactions, 65% of patients had grade I thrombocytopenia, and 24% of patients had grade I anaemia. After completion of treatment 65% of patients had complete response at the primary and regional sites, and 35% of patients had a partial response of whom 23% underwent neck dissection and 5% of them underwent salvage surgery at the primary site. At the end of one year there were six deaths and four recurrences and 70% were free of disease. Concurrent chemoradiation with carboplatin provided good locoregional control for locally advanced head and neck cancers. This regimen, although toxic, is tolerable with appropriate supportive intervention. Primary site conservation is possible in many patients. Chemoradiotherapy appears to have an emerging role in the primary management of head and neck cancers.

Purpose : To analyse clinical outcome and prognostic factors according to treatment modality, this paper report our experience of retrospective study of patients with esophageal cancer Materials and Methods : One hundred and ten patients with primary esophageal cancer who were treated in Presbyterian Medical Center from May 1985 to December 1992. We analysed these patients retrospectively with median follow up time of 28 months, one hundred and four patients($95{\%}$) were followed up from 15 to 69 months. In methods, twenty-eight patients were treated with median radiation dose irradiated 54.3Gy only. Fifty-six patients were treated with combined chemoradiotherapy. Sixteen cases of these patients were treated with concurrent chemoradiation and the other patients(forty cases) were treated sequential chemoradiotherapy. In concurrent chemoradiotherapy group, patients received 5-FU continuous IV infusion for 4 days. Cisplatin IV bolus. and concurrent esophageal irradiation to 30 Gy. After that patients received 5-FU continuous IV, Cisplatin bolus injection and Mitomycin-C bolus IV, Bleomycin continuous IV, and irradiation to 20 Gy. In sequential chemoradiotherapy group, the chemotherapy consisted of 5-FU 1,000mg/$m^2$ administered as a continuous 24 hour intravenous infusion during five days and Cisplatin 80-100mg/$m^2$ bolus injected, or Bleomycin, Vinblastine, Cisplatin, Methotrexate were used of 1 or 2 cycles. After preoperative concurrentm chemoradiation twenty-six patients underwent radical esophagectomy. Results : Ninety-three patients could be examined for response assessment, By treatment modality, response rates were $85.1{\%}$ for radiation alone group and $86.3{\%}$ for combined chemoradiation group. But in operation group, after one cycle of concurrent chemoradiation treatment, response rate was $61.9{\%}$. The pathologic complete response were $15.4{\%}$ in operation group. Overall median survival was II months and actuarial 5-year survival rate was $8{\%}$. The median survival interval was 6 months for radiation alone group, 11 months for combined chemoradiation group and 19 months for operation group. And also median survival was 19 months for complete responder group that 8 months for noncomplete responder group. In univariative analysis, statistically significant prognostic factors were tumor size, clinical stage, tumor response, and operation. In multivariative analysis, significantly better survival was associated with clinical stage, tumor response, radiation dose, and operation. Conclusion : Compared with radiotherapy alone, combined multimodality may improve the median survival in patients with localized carcinoma of the esophagus and toxicity is acceptable.

연구배경 : 최근 항암화학요법과 방사선요법의 병용치료는 국소진행성 비소세포폐암 치료에 있어서 표준치료방법으로 자리잡고 있으며 동시요법이 순차적요법에 비해 치료반응율에 있어서 우수하다고 알려져 있다. 본 연구는 비소세포폐암 치료에 있어서 우수한 효과를 보이고 방사선감작 효과가 있다고 알려진 paclitaxel (60 $mg/m^2$) 매주투여와 동시 방사선요법의 III병기 비소세포폐암 환자에서의 치료효과와 독성을 조사하기 위하여 시행하였다. 방 법 : III병기 비소세포폐암 환자 22명 (IIIA:6, IIIB:16)을 대상으로 paclitaxel (60 $mg/m^2$)을 제 1, 8, 15, 22, 29, and 36일째에 매주 투여하고 동시에 54 Gy의 방사선 치료를 시행하였다. 초기 동시치료를 종료하고 paclitaxel (175 $mg/m^2$)/cisplatin (75 $mg/m^2$) 혹은 paclitaxel (175 $mg/m^2$)/carboplatin (6AUC) regimen 으로 보강화학요법을 3주 간격으로 2주기 시행하였다. 결 과 : 전반적 치료반응율은 81.8% (18/22)로서 완전관해가 9.1% (2/22), 부분관해가 72.7% (16/22)의 결과를 보였다. 두명의 (9.1%) 환자가 치료종료 후 방사선폐장염의 합병증으로 사망하였다. 3도 이상의 독성 반응은 방사선폐장염 (22.7%), 식도염 (22.7%), 신경병증 (13.6%), 및 백혈구감소증 (13.6%)의 결과를 나타내었다. 중앙생존기간은 15개월이었고 1년 및 2년 생존율은 각각 63.6%와 31.8%였다. 결 론 : 국소진행성 비소세포폐암 환자에서 paclitaxel 매주 투여에 의한 동시 방사선요법은 우수한 종양반응율을 나타내지만 치명적인 방사선폐장염의 발생 위험이 있으므로 향후 보완연구가 필요할 것으로 사료된다.

식도암의 치료는 근치적 절제와 화항방사선치료를 포함하는 다중치료가 보편적으로 받아들여지고 있다. 그러나 치료의 종양학적 결과는 충분히 만족스러운 수준에 이르고 있지 못하다. 이에 대하여 기존 항암 화학요법과 방사선치료, 수술 그리고 표적약물의 적용에 대한 연구가 지속되고 있다. 이 논문에서는 문헌과 보고를 근거로 식도암 치료에 대한 최근의 합의과 권고를 정리하였다.

Background: The optimal sequence and extent of multimodality therapy remains to be defined for extrapulmonary small cell carcinoma because of its rarity. The purpose of our study was to assess the response to neoadjuvant chemotherapy followed by chemoradiation/radiation in patients with extrapulmonary small cell carcinoma. Materials and Methods: Four consecutively diagnosed patients were included in this study. The primary tumor site was oropharynx in three patients and esophagus in one. The patients with the limited disease were treated with chemotherapy followed by concurrent chemoradiation (n=2) or radiotherapy (n=1). The patient with the extensive disease with the primary site in vallecula was treated with chemotherapy and palliative radiotherapy to the metastatic site. Results: The median follow-up was 22.5 months (range, 8-24 months). Three patients with the limited disease (base of tongue, n=2; esophagus, n=1) were in complete remission. The patient with the extensive disease died of loco-regional tumor progression at 8 months from the time of diagnosis. Conclusions: The combination of chemotherapy and radiotherapy is the preferred therapeutic approach for patients with extrapulmonary small cell carcinoma. Induction chemotherapy followed by concurrent chemoradiation or radiation provides a good loco-regional control in patients with limited disease.
