Purpose : To improve the therapeutic results of Postoperative recurrent disease and
inoperable disease of stomach cancer, we used the thermoradiotherapy. We conducted a
retrospective analysis of the results and compared the results of hyperthermia before
radiotherapy and those of hyperthermia after radiotherapy.
Materials and Methods : From July 1994 to November 1996, we treated twenty
patients with locally advanced stomach cancer and recurrent stomach cancer with
thermoradiotherapy. We divided those Patients into two groups hyperthermia before
radiotherapy group (PreRT group : 13 patients) and hyperthermia after radiotherapy
group (PostRT group: 7 patients). We performed radiation therapy with the total tumor
dose of 3000-5040cGy in a fraction of 180-300c0y and 5 fractions per week.
Hyperthermia was performed with 8 MHz radiofrequency apparatus. PreRT group
patients were treated daily for 30 minutes before the radiation therapy within the
interval of ten minutes. And PostRT group patients were treated with 1-2 sessions per
week for 40-60 minutes after the radiation therapy within the interval of 10 minutes.
Results : Overall response rate was 33.3%. This response rate appeared the same in
both grouts. Mean survival and 1 years survival rate were 10.3 months and 16.5%. In
PreRT group, mean survival and 1 year survival rate were 6.8 months and 9.0%, and in
PostRT group, mean survival and 1 year survival rate were 7.7 months and 34%. There
were no statistically significant difference between the prognostic factors and therapeutic
results.
Conclusion : The thermoradiotherapy was a safe treatment method in advanced and
recurrent gastric cancer when compared with other treatment. Because the number of
patients we treated was small and the follow up period was short, we were not able to
draw any conclusions about the therapeutic efficacy of the sequence of radiation therapy
and hyperthermia. Therefore, further clinical trials of thermoradiotherapy for stomach
cancer appear to be warranted.
