Resection and reconstruction of the chest wall for the radical surgical treatment of malignant soft tissue tumors are currently considered a substantial challenge for thoracic surgeons. We present an unusual case of infantile fibrosarcoma with tropomyosin 3-neurotrophic receptor tyrosine kinase 1 fusion in a 13-year-old patient. The surgical treatment consisted of radical resection of the right posterior chest wall and reconstruction with the use of the STRATOS (Strasbourg Thoracic Osteosynthesis System) titanium rib bridge system. The patient had a favorable postoperative course and received respiratory-ventilatory rehabilitation, adjuvant therapy with chemotherapeutic agents, immunotherapy, and radiotherapy.
Primary cerebellar glioblastoma multiforme (GBM) is a rare tumor in adults that accounts for just 1% of all cases of GBM. Due to their rarity, cerebellar GBMs are not yet completely understood about the pathogenesis and the prognosis. Here, we present a case of GBM in a 69-year-old man. Neurologic examination revealed the presence of cerebellar signs. Magnetic resonance imaging (MRI) showed a 4.5${\times}$3.6 cm-sized, ill-defined, heterogeneously enhancing mass in the left cerebellum and two patchy hyperintense lesions in the right cerebellum with minimal enhancement. After operation, glioblastoma was histologically confrimed. Postoperative radiotherapy with concomittent and adjuvant temozolomide chemotherapy was subsequently followed. Here, a case of unusual GBM in the cerebellum is reported with review of literature regarding the pathogenesis, the differential diagnosis and prognosis. There was no evidence of recurrence during postoperative one year. This patient showed a good prognosis in spite of the multiple lesions.
Purpose: This retrospective study was conducted to assess outcome and to determine the prognostic factors in patients with a desmoid tumor treated with postoperative radiotherapy. Materials and Methods: Twenty-seven patients with a desmoid tumor who were treated with postoperative radiotherapy between June 1984 and October 2005 were analyzed. There were 13 male and 14 female patients. The age of the patients ranged from 3 to 79 years (median age, 28 years). Tumors were located in an extra-abdominal area (21 cases), and in the abdominal walls (6 cases). The tumor size ranged from 2.5 to 25 cm (median size, 7.5 cm) in the largest linear dimension. Thirteen cases received radiotherapy after initial surgery, and 14 recurrent cases received radiotherapy after additional surgery. The total radiation dose given was $45{\sim}66$ Gy (median dose, 59.4 Gy), and the fraction size was $1.8{\sim}2.0$ Gy. Results: The median follow-up period was 61 months (range, $12{\sim}203$ months). Two patients developed local progression and six patients experienced local recurrence. The 5-year disease-free survival rate and the 5-year progression-free survival rate were 61 % and 70%, respectively. Wide local excision was associated with better disease free survival with statistical significance (p=0.028). Radiotherapy after initial surgery (p=0.046) and a higher radiation dose of more than 60 Gy (p=0.049) were associated with better progression free survival with statistical significance. At the time of the last follow-up, the number of additional surgeries was higher in patients that received radiotherapy after reoperation (p<0.001). Conclusion: Radiotherapy after the initial operation improved local control and decreased the number of subsequent operations. Thus, postoperative radiotherapy after an initial operation is recommended in patients with a high risk of recurrence for a desmoid tumor.

Purpose: The aim of this study was to identify the change in hand grip strength (HGS) for consecutive 6 months in breast cancer survivors (BCS) undergoing postoperative adjuvant chemotherapy (adjCTX) and to determine the factors relevant to HGS after chemotherapy completion Methods: This study was a retrospective observational cohort study. BCS (N=38) who underwent breast cancer surgery and subsequent adjCTX were enrolled. The HGS of both sides was measured before adjCTX and 3 weeks, 2 months and 6 months after adjCTX. And we also collected body composition, anthropometric measurements, social demographics and clinical data. Then we analyzed the changes in HGS over time, and correlation of collected data with HGS at 6 months. Results: A significant increase in HGS of the unaffected side was observed within the first 3 weeks of adjCTX and maintained up to 6 months. In correlation analysis, HGS of both sides was positively correlated with the ipsilateral HGS at 3 weeks, and contralateral HGS at 6 months. And skeletal muscle mass was also positively correlated with the HGS of the unaffected side. In addition, subjects treated with targeted therapy had lower HGS of the unaffected side. However, HGS of the affected side was significantly lower in subjects with breast reconstruction and treated without radiotherapy. Conclusions: To maintain the early recovery of HGS, active and continuous exercise intervention for strengthening might be necessary.
Purpose : To evaluate the role of postoperative radiation therapy after curative resection of sigmoid colon cancer Materials and Methods : From 1988 to 1993, a total of 93 Patients with curative resectable sigmoid colon cancer of modified Astler-Coiler (MAC) stage B2, B3, C2, C3 was divided into two groups on the basis of those who received radiation treatment and those who did not. Forty-three patients who treated by surgery alone were classified as postop RT (-) group The remaining 50 patients who underwent postoperative radiotherapy were classified as postop RT (+) group. In all patients in Postop RT (+) group. radiation therapy was delivered using 4 or 10 MV linear accelerators to treat the tumor bed with approximately 5cm margin to a total dose 50.4-61Gy(median 54Gy) in 1.8Gy per fraction. Thirty-two patients were treated. with 5-Fluorouracil based adjuvant chemotherapy at least 3 cycles. but these was no significant difference between two groups. Treatment failure Pattern, 5-year local failure-free survival rates (LFFS), and 5-year disease-free survival rates (DFS) were compared between two groups. Result : Five year LFFS and DFS were $85.1\%,\;68.5\%$, respectively, In Postop RT (-) group, LFFS was $76.2\%$ compared with $91.7\%$ in Postop RT (+) group. Improved LFFS and DFS were seen for patients with stage C3 sigmoid colon carcinoma with postoperative radiation therapy compared with postop RT (-) group (P=0.01, p=0.06 respectively), in stage B3, LFFS washigher in postop RT (+) group than that in Postop RT (-) group. although itwas not significant. Especially, local control was higher in stage 74 inpostop RT (+) group than that in postop RT (-) group, Conclusion : This studv showed significantly improved LFFS and DFS in MAC Stage C3 and improved tendency of LFFS and DFS in MAC Stage B3 disease. Large scale prospective study is required to verify the role of adjuvant radiation therapy in resectable sigmoid colon cancer.
[ $\underline{Purpose}$ ]: To evaluate the role of postoperative adjuvant chemoradiotherapy in rectal cancer, we retrospectively analyzed the treatment outcome of patients with rectal cancer taken curative surgical resection and postoperative adjuvant chemoradiotherapy. $\underline{Materials\;and\;Methods}$: A total 46 patients with AJCC stage II and III carcinoma of rectum were treated with curative surgical resection and postoperative adjuvant chemoradiotherapy. T3 and T4 stage were 38 and 8 patients, respectively. N0, N1, and N2 stage were 12, 16, 18 patients, respectively. Forty patients received bolus infusions of 5-fluorouracil ($500\;mg/m^2/day$) with leucovorin ($20\;mg/m^2/day$), every 4 weeks interval for 6 cycles. Oral Uracil/Tegafur on a daily basis for $6{\sim}12$ months was given in 6 patients. Radiotherapy with 45 Gy was delivered to the surgical bed and regional pelvic lymph node area, followed by $5.4{\sim}9\;Gy$ boost to the surgical bed. The follow up period ranged from 8 to 75 months with a median 35 months. $\underline{Results}$: Treatment failure occurred in 17 patients (37%). Locoregional failure occurred in 4 patients (8.7%) and distant failure in 16 patients (34.8%). There was no local failure only. Five year actuarial overall survival (OS) was 51.5% and relapse free survival (RFS) was 58.7%. The OS and RFS were 100%, 100% in stage N0 patients, 53.7%, 47.6% in N1 patients, and 0%, 41.2% in N2 patients (p=0.012, p=0.009). The RFS was 55%, 78.5%, and 31.2% in upper, middle, and lower rectal cancer patients, respectively (p=0.006). Multivariate analysis showed that N stage (p=0.012) was significant prognostic factor for OS and that N stage (p=0.001) and location of tumor (p=0.006) were for RFS. Bowel complications requiring surgery occurred in 3 patients. $\underline{Conclusion}$: Postoperative adjuvant chemoradiotherapy was an effective modality for locoregional control of rectal cancer. But further investigations for reducing the distant failure rate are necessary because distant failure rate is still high.

Purpose: To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. Materials and Methods: Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using $^{192}Ir$ between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment and in five patients as salvage treatment for recurrence after the initial surgery. In 12 patients, external beam radiotherapy (50-55 Gy/25 fractions) was combined with IBT of 21 Gy/7 fractions. In addition, IBT was administered as the sole treatment in three patients with a total dose of 50 Gy/10 fractions and as postoperative adjuvant treatment in one patient with a total of 35 Gy/7 fractions. Results: The 5-year overall survival of the entire group was 70%. The actuarial local control rate after 3 years was 84%. All five recurrent cases after initial surgery were successfully salvaged using IBT ${\pm}$ external beam radiotherapy. Two patients developed local recurrence at 3 and 5 months, respectively, after IBT. The acute complications were acceptable (${\leq}grade$ 2). Three patients developed major late complications, such as radio-osteonecrosis, in which one patient was treated by conservative therapy and two required surgical intervention. Conclusion: HDR IBT for oral cavity cancer was effective and acceptable in diverse clinical settings, such as in the cases of primary or salvage treatment.
Purpose: To investigate treatment outcome and long term complication after surgery and radiotherapy (RT) for pituitary adenoma. Materials and Methods: From 1990 to 2009, 73 patients with surgery and RT for pituitary adenoma were analyzed in this study. Median age was 51 years (range, 25 to 71 years). Median tumor size was 3 cm (range, 1 to 5 cm) with suprasellar (n = 21), cavernous sinus extension (n = 14) or both (n = 5). Hormone secreting tumor was diagnosed in 29 patients; 16 patients with prolactin, 12 patients with growth hormone, and 1 patient with adrenocorticotrophic hormone. Impairment of visual acuity or visual field was presented in 33 patients at first diagnosis. Most patients (n = 64) received RT as postoperative adjuvant setting. Median RT dose was 45 Gy (range, 45 to 59.4 Gy). Results: Median follow-up duration was 8 years (range, 3 to 22 years). In secreting tumors, hormone normalization rate was 55% (16 of 29 patients). For 25 patients with evaluable visual field and visual acuity test, 21 patients (84%) showed improvement of visual disturbance after treatment. The 10-year tumor control rate for non-secreting and secreting adenoma was 100% and 58%, respectively (p < 0.001). Progression free survival rate at 10 years was 98%. Only 1 patient experienced endocrinological recurrence. Following surgery, 60% (n = 44) suffered from pituitary function deficit. Late complication associated with RT was only 1 patient, who developed cataract. Conclusion: Surgery and RT are very effective and safe in hormonal and tumor growth control for secreting and non-secreting pituitary adenoma.

Purpose: To identify prognostic factors influencing progression-free survival (PFS) of aggressive fibromatosis (AF) after postoperative radiotherapy (PORT) and assess correlations between immunohistochemistry (IHC) features of β-catenin/smooth muscle actin (SMA) and PFS. Materials and Methods: Records of 37 patients with AF treated by PORT from 1984 to 2015 were retrospectively reviewed. Fifteen patients underwent wide excision for AF and 22 patients received debulking operation. The median total dose of PORT was 59.4 Gy. IHC staining results of β-catenin and SMA were available for 11 and 12 patients, respectively. Results: The median follow-up duration was 105.9 months. Five-year PFS rate was 70.9%. Tumor size or margin status was not related to PFS in univariate analysis (p = 0.197 and p = 0.716, respectively). Multivariate analysis showed that increased interval from surgery to PORT (>5.7 weeks) was a marginal risk factor for PFS (p = 0.054). Administration of PORT at the initial diagnosis resulted in significantly improved PFS compared to deferring PORT after recurrence (p = 0.045). Patient with both risk factors of deferring PORT after recurrence and interval from surgery to PORT >5.7 weeks had significantly lower 5-year PFS than patients without risk factor (34.1% vs. 100.0%; p = 0.012). Nuclear β-catenin intensity tended to inversely correlate with 5-year PFS, although it did not reach statistical significance (62.5% at low vs. 100.0% at high; p = 0.260). SMA intensity was not related to PFS (p = 0.700). Conclusion: PORT should be performed immediately after surgery irrespective of margin status or tumor size especially in recurrent case. Nuclear β-catenin staining intensity of IHC might correlate with local recurrence.
Background: To evaluate treatment outcomes of patients with stage I-III endometrial cancer treated with postoperative radiation. Materials and Methods: A retrospective review of 166 endometrial cancer patients, undergoing surgery and postoperative radiotherapy at Siriraj Hospital from 2005-2008 was performed. Pathology was reviewed. Results of treatment were reported with 5-year loco-regional recurrence free survival (LRRFS), 5-year overall survival (OS), patterns of failure and toxicity, and according to stage and risk groups. Results: Median follow up time was 62.8 months. Pathological changes were found in 36.3% of the patients after central reviews, leading to 19% changes in risk groups. Most of the patients (83.7%) received pelvic radiation (PRT) and vaginal brachytherapy (VBT). Five-year LRRFS and OS of all patients were 94.9% and 85.5%, respectively. There was no recurrence or death in low and low-intermediate risk groups. For the high-intermediate risk group, 5-year LRRFS and OS were 96.2% and 90.8%, respectively, and for the high risk group 90.5% and 71%. Late grade 3 and 5 gastrointestinal toxicity was found in 3% and 1.2% of patients, respectively. All of them received PRT 5,000 cGy in 25 fractions. Conclusions: Low and intermediate risk patients had good results with surgery and adjuvant radiation therapy. For high risk patients, postoperative radiation therapy alone appeared to be inadequate as the most common pattern of failure was distant metastasis.
