PURPOSE: To improve the treatment results of locally advanced nonsmallcell lung cancer (NSCLC) patient, we treated those paients with regional hyperthermia combined with radiotherapy. And we conducted a retrospective analysis of the results. METHODS AND MATERIALS: Thirty two nonsmall cell lung cancer patients treated at the Department of Radiation Oncology, St. Mary's hospital. Catholic University Medical College were the base of this analysis. Fourteen patients of above them were treated with hyperthermia and radiotherapy of more than 3000 cGy in radiation dose. Radiofrequency capacitive hyperthermia was administered twice weekly, immediately after radiotherapy. Total sessions of hyperthermia ranged from 3 to 13 times (mean 7,8). Eighteen patient received an external radiation therapy alone. Median radiation dose was 5580 cGy (range, 3000-7000 cGy) in fraction of 180-300 cGy, 5 fractions per week. RESULTS: The results of themoradiotherapy group (HTRT group) were compared with radiation alone group (RT group). There were no complete response (CR) and 12 partial responses (PR) (CR rate 0%, response rate 85.7%) in HTRT group, whereas there were 2 CRs, 8 PRs and 8 no responses (CR rate 11.1%, response rate 55.6%) in RT group. There was significant differece in local response rate of the tumors between RT group and HTRT group (p<0.05). Overall 2 year survival rate and mean survival were 7.1% and 10.5 months for HTRT group, and 0% 8.1 months for RT group. However, by the number of hyperthermia, in cases with more than or equal to 10 sessions of hyperthermia, there were significant improvement in 2 year survival rate and mean survival (40.0% and 18.2 months) compared with those in cases with less than 10 sessions of hyperhtemia (7.4% and 7.4 months) (p<0.05). CONCLUSION: Thermoradiotherapy in locally advanced NSCLC patients increased their response rate but not 2 year survival and mean survival, therefore thermoradiotherpy with enough number of hyperthermia is suggested that may be one of the effective palliative treatments of those patients. And in cases with more than 10 sessions of hyperthermai, there showed improved 2 year survival rate and mean survival. But the number of the cases was small, further study in this aspect is required.

PURPOSE: To correlate the pathologic and MR findings of distal femoral cortical irregularity(DFCI) in adult. MATERIALS AND METHODS: We retrospectively reviewed knee MR images of 120 adult patients(25-62 years old) without infection, tumor, or fracture. Five femoral specimens of adult cadaver were used to correlate pathologic and MR findings. A double cortical line' on MR images was interpreted as DFCI, and MR findings were analyzed to determine the thickness, internal signal intensity, location of the DFCI, shape of the external cortex, and clarity of the inner cortex. The outer cortex was classified as either convex or flat, and the inner cortex was classified according to its thickness and continuity as one of three types. RESULTS: One hundred and sixteen patients(97%) had DFCI, which in all cases was observed at the attachment site of the medial head of the gastrocnemius muscle. Mean thickness was 3.7mm and DFCI was thicker in men than in women(p<0.05). The outer cortex was convex in 75 cases(65 %) and flat in 41(35 %). The inner cortex was thick and continuous in 47cases(41 %, mean age 31), thin and continuous in 54(47 %, mean age 38), and thin and discontinuous in 19(16 %, mean age 47). Clarity tended to diminish with age. The internal area of DFCI showed signal intensity equal to that of adjacent bone marrow and was pathologically proven to be normal marrow tissue. CONCLUSION: DFCI was observed in most adults and was considered to be a normal variation. Its MR and pathologic findings were different to those observed during periods of growth.
