Objective To evaluate the results and side effects in three dimensional conformal radiation therapy (3DCRT) for esophageal carcinoma. Methods From December 1996 to December 1998,67 patients with esophageal carcinoma were treated with 3DCRT(3DCRT group),in which all were treated once every other day to a total dose of 40 42 ?Gy in 13 15 days at 5 6?Gy per fraction totally 7 8 fractions, and during the same interval, another 112 patients treated by conventional fractionation radiotherapy(CF group) to a total dose of 64 68?Gy over 44 48 days at 2.0?Gy per fraction 5 days per week were analyzed and compared. Results The 1 ,2 ,3 and 4 year local control rates in 3DCRT group were 71.6% ,62.7%,49.3% and 43.3% ,compared to 53.6%, 43.8% ,33.9% and 25.9% in CF group (P = 0.011). And the survival rates in 1 ,2 ,3 and 4 years in 3DCRT group were 62.7%,52.2%,43.3% and 38.8%, as compared with 49.1%, 41.1% ,30.4% and 22.3% in CF group (P = 0.027). However, in the 3DCRT group, the incidence of acute radiation esophagitis was higher (P=0.003) and those of hematogenous side effects and B symptom were lower(P=0.007,0.021). Conclusion Compared with conventional fractionation radiotherapy,3DCRT is able to improve the local control rate of esophageal carcinoma, with tolerable acute and late radiation side effects.

Objective To investigate the clinical effect of lentinan and thymopentin injection combined with PTP chemotherapy in oral squamous cell carcinoma patients, and to observe the effect of lentinan on serum tumor specific growth factor ( TSGF) , IgG, IgA and IgM and quality of life in patients with oral squamous cell carcinoma .Methods The clinical data of 80 cases of oral squamous cell carcinoma ( postoperative lymph node metastasis) confirmed by operation and pathology were analyzed retrospectively, and the diagnosis and treatment were analyzed.The control group were treated with PTP regimen, 80 ~120 mg/m2 of cisplatin, 50 ~80 mg/m2 of teniposide on the first day, the second to fourth day, once daily +pingyangmycin 4~6 mg/m2 , once daily, 3 to 12 days, 3 weeks for a course of treatment, a total of 6 courses.In the control group based on the use of thymopentin injection 20 mg and lentinan 2 mg+5% glucose solution 250 mL intravenous infusion, chemotherapy 2 d before the start, infusion 14 d, 3 weeks for a course of treatment, a total of 6 courses, for the observation group;two groups were 40 cases.The levels of serum TSGF, IgA, IgG, IgM and CD3 +, CD4 +, CD8 +, NK cells and TSGF in the two groups before and after treatment were measured.The quality of life of the patients was investigated by hospital-made questionnaires.The clinical efficacy and side effects were analyzed.Results TSGF levels in the two groups were significantly lower than that before treatment, and the TSGF level in the observation group was (39.1 ±4.9)U/mL, which was significantly lower than that in the control group (52.3 ±5.8) U/mL(P<0.05).After treatment, the TSGF level in observation group was lower than that in control group [(39.1 ±4.9) U/mL vs. (52.3 ±5.8) U/mL](P<0.05).The CD3 +, CD4 +, NK, IgG levels in observation group were higher than those in control group and the CD8 +level in observation group was lower than that in control group (P<0.05).The scores of physical symptoms, sleep quality, mental state and social affection levels in observation group were higher than those in control group(P<0.05).The total efficacy in observation group was lower than that in control group (77.5% vs.45.0%, P<0.05).The adverse reaction rate was 20.0% in the observation group, which was significantly lower than that in the control group (P<0.05).Conclusion The use of lentinan and thymopentin injection combined with PTP chemotherapy in the treatment of oral squamous cell carcinoma has higher clinical efficacy and less adverse reactions.
