The clinical results after carbon ion radiotherapy for the metastatic lung tumors believed to be in the state of oligo-recurrence were evaluated. One hundred and sixteen lesions in 91 patients with lung cancer metastasis were treated with carbon ion radiotherapy at our institute from April 1997 to February 2011. Regarding the prescribed dose, total dose ranged between 40 gray equivalents (GyE) and 80 GyE, and fraction size ranged from 1 to 16 fractions. After a median followup period of 2.3 years (range, 0.3–13.1 years), the statistical overall survival rate and local control rate were 71.2% and 91.9% at 2 years after treatment, respectively. Treatment-related side effects were not a clinical problem. When classified by the primary organ, there were 49 cases of lung cancer, 20 cases of colorectal cancer, and 22 cases of others. The overall survival rate and local control rate for lung metastasis cases from lung cancer at 2 years after treatment were 81.5% and 92.4%, respectively, and 65.0% and 92.0% regarding lung metastasis from colorectal cancer. Carbon ion beam therapy for the metastatic lung tumors is a safe therapy, and the therapeutic effect is comparable to the outcome obtained from reported surgical resections.

Forty-eight untreated patients with early supraglottic carcinoma (12 patients stage I and 36 patients stage II) had primary carbon dioxide laser microsurgery between 1979 and 1994 with the intent of complete tumor removal with preservation of functionally important structures of the larynx. Ninety-six percent of the patients were treated exclusively by surgery; 4% had laser microsurgery and postoperative radiotherapy. With a median follow-up of 55 months, the 5-year local control rate with the first treatment was 100% for pT1 cases and 89% for pT2 cases. The ultimate local control rate with voice preservation, including patients successfully salvaged after a local recurrence, was 97% for pT2 carcinomas. Five (10%) patients died of tumor (TNM)–related deaths. The 3-year recurrence-free rate and 3-year overall survival rate (Kaplan-Meier) were 87% and 85%; the 5-year recurrence-free rate and 5-year overall survival rate were 83% and 76%, respectively. The results achieved with transoral laser microsurgery in early supraglottic carcinoma are comparable to those of open supraglottic laryngectomy with respect to local control and survival. The functional results are superior, since clinically relevant aspiration did not occur.

Background: MBNL1, a protein encoded by q25 gene on chromosome 3, belongs to the tissue-specific RNA metabolic regulation family, which controls RNA splicing.[1]MBNL1 formed in the process of development drive large transcriptomic changes in cell differentiation,[2] it serves as a kind of tumor differentiation inhibitory factor.MBNL1 has a close relationship with cancer, comprehensive analysis, [3]found that breast cancer, leukemia, stomach cancer, esophageal adenocarcinoma, glial cell carcinoma and another common tumor in the cut, and cut in Huntington's disease. But MBNL1 plays a promoting role in cervical cancer, is contradictory in colorectal cancer, It promotes colorectal cancer cell proliferation, On the other hand, it inhibits its metastasis, so it is an important physiological marker in many cancers. When we integrated the role of MBNL1 protein in various tumors, we found that its antisense RNA, MBNL1-AS1, had a good inhibitory effect in several colorectal cancer, non-small cell lung cancer, and gastric cancer. Objective: To elucidate the expression of MBNL1 and MBNL1-AS1 in various tumors, and to search for their physiological markers. Methods: It was searched by the PUMUB system and summarized its expression in various cancers. Results: MBNL1 was down-regulated, leukemia, breast cancer, glioblastoma, gastric cancer, overall survival rate, recurrence, metastasis increased. While the metastasis of colon cancer decreased, proliferation was promoted, and the effect of both was promoted for cervical cancer.MBNL1-AS1 was down-regulated, and the overall survival rate, recurrence, and metastasis of lung cancer, colorectal cancer, and bladder cancer increased. Conclusion: MBNL1 may be an important regulator of cancer, and MBNL1-AS1 is a better tumor suppressor.

Background. The aim was to investigate the potential factors related with overall survival of oligometastatic non-small-cell lung cancer (NSCLC) patients. Methods. A literature search was conducted in databases including PubMed, Embase, and Cochrane library up to March 2017. The hazard radio (HR) as well as the corresponding 95% confidence interval (CI) were calculated, and all the statistics analysis was performed by the R 3.12. Heterogeneity was analyzed using I-squared and Cochran Q tests. Furthermore, sensitivity analysis was performed to evaluate the stability of results. Results. In total, 6 articles were included in the meta-analysis. Nodal status was significantly correlated with the overall survival rate of NSCLC oligometastatic patients (HR: 1.69, 95% CI: 1.23–2.32, Z=3.20, P=0.001). No significant relationship was found between overall survival rate of NSCLC oligometastatic patients and the indicators including sex, stage, smoker, age, and histology. Notably, sensitivity analysis on data evaluating relationship between patients survival and the stage and histology showed that results were reversed after removing one of the studies. Conclusions. Nodal status might be associated with the overall survival of oligometastatic NSCLC patients.

7623 Background: Stereotactic radiotherapy (SRT) has been aggressively performed as a radical treatment for stage I non-small cell lung cancer (NSCLC) in Japan, however most cases were medically inoperable. In a large Japanese multi-institutional experience, we reviewed the treatment outcome of SRT for medically operable stage I NSCLC cases with the patients’ refusal to surgery. Methods: In 1995–2004, 86 medically operable patients with stage I NSCLC (median age, 74 years; 62 T1N0M0; 24 T2N0M0) were treated with SRT alone in 14 reliable institutions. Stereotactic three-dimensional treatment was performed using non-coplanar dynamic arcs or multiple static ports. A total dose of 20 to 72.5 Gy at the isocenter was administered in 1 to 10 fractions. Median calculated biological effective dose (BED) was 115 Gy (range, 100–153 Gy). The data was collected and analyzed in a retrospective manner. Results: During follow-up (median, 43 months), pulmonary complications of above grade 2 arose in 4 patients (5.8%). Local control rates at 3 and 5-year post SRT were 88.1% and 85.5%, respectively. Three and 5-year overall survival rates were 80.7% and 71.3%, respectively. Five-year overall survival rate for patients whose age was over 70 years (n=27) and under 70 years (n=58) were 74.3% and 69.6%, respectively. Five-year overall survival rate for stage IA (n=62) and IB (n=24) cases were 72.3% and 68.4%, respectively. Conclusions: SRT is safe and promising as a radical treatment for operable stage I NSCLC. The survival rate of SRT is potentially comparable to that of surgery. No significant financial relationships to disclose.

PurposeEffective treatment strategies for unresectable locally advanced pancreatic cancer (LAPC) patients are eagerly warranted. Recently, convincing oncological outcomes were demonstrated by carbon ion radiotherapy. Nevertheless, there is a lack of evidence for this modern radiation technique due to the limited number of carbon ion facilities worldwide. Here, we analyze feasibility and efficacy of carbon ion radiotherapy in the management of LAPC at Heidelberg Ion Beam Therapy Center (HIT).MethodsBetween 2015 and 2020, 21 LAPC patients were irradiated with carbon ions with a total dose of 48 Gy (RBE) in single doses of 4 Gy (RBE). Three patients (14%) were treated with concomitant chemotherapy with gemcitabine 300 mg/m2 body surface weekly. Toxicity rates were extracted from the charts. Overall survival, progression free survival, local control, and locoregional control were evaluated using Kaplan–Meier estimates.ResultsOne patient developed ascites CTCAE grade III during radiotherapy, which was related to a later histologically confirmed metachronous peritoneal carcinomatosis. No further higher-graded toxicity could be observed. The most common symptoms were nausea and abdominal pain. After a median estimated follow-up time of 19.1 months, the median progression free survival was 3.7 months, and the median overall survival was 11.9 months. The estimated 1-year local control and locoregional control rates were 89 and 84%, respectively.ConclusionCarbon ion radiotherapy of LAPC patients is safely feasible. Local tumor control rates were high. Nevertheless, compared to historical data, an overall survival improvement could not be observed. This could be explained by the poor prognosis of the selected underlying patients that mostly did not respond to prior chemotherapy as well as the early and frequent emergence of distant metastases that demonstrate the necessity of additional chemotherapy in further studies.

The frequency of smoking among patients with primary lung cancer diagnoses admitted to the Hospital de Clinicas de Porto Alegre (HCPA) during the 1980's was investigated. The objective of this study was to analyze cigarette consumption patterns through the number of cigarettes smoked per day and the age at which smoking began, correlating this data to the overall survival rate and histological type of the lung cancer. Methods: This retrospective study analyzed patients with primary lung cancer diagnosed at the HCPA between January 1980 and December 1989. All patients considered underwent follow-up for at least three years. Patient information was obtained either from the hospital's records or by contacting patients via letter or phone. Results: More than 90 percent of the patients were smokers or had smoked previously; most had started smoking before the age of 20.The overall 24-month survival rate after diagnosis varied depending on whether the patient had smoked less than 40 cigarettes per day or not. The percentage of smokers and non-smokers was established for each histological type, with the bronchoalveolar adenocarcinoma type showing the highest percentage of non-smokers (40 percent). Conclusion:The overall survival rates of patients with lung cancer was related to the number of cigarettes smoked, and not to the fact of the patient having smoked or not.The number of smokers among patients with lung cancer was not so high only for the bronchoalveolar adenocarcinoma histological type.

Abstract The purpose of this study was to evaluate the efficacy and toxicities of carbon-ion radiotherapy (C-ion RT) for locally advanced cervical cancer with bladder invasion by a subset analysis of pooled data from eight prospective clinical trials at the National Institute of Radiological Sciences. Between June 1995 and January 2014, 29 patients with locally advanced cervical cancer with bladder invasion were identified. The median age was 56 years old (range 31–79 years old). The median tumor size at diagnosis on magnetic resonance imaging was 6.7 cm (range 3.5–11.0 cm). Histologically, 20 patients had squamous cell carcinoma and 9 had adenocarcinoma. C-ion RT was performed as a dose-escalation study in the initial trials. All patients received prophylactic whole-pelvic or extended-field irradiation and local boost. The total dose to the cervical tumor was 52.8–74.4 Gy (relative biological effectiveness) in 20 or 24 fractions. Weekly cisplatin (40 mg/m2/week, five cycles) was concurrently given to four patients. The median follow-up of all patients was 28.6 months (range 8.8–238.6 months). Grade 2 or higher late complications in the bladder were observed in eight patients, with seven developing vesicovaginal fistula. Six patients had Grade 2 or higher complications in the rectosigmoid colon. The 3-year overall survival rate was 47%, the 3-year local control rate was 66%, and the 3-year disease-free survival rate was 28%. In this study, C-ion RT showed favorable local control with reasonable toxicities, but the results were still unsatisfactory. We have the expectation of improvement of therapeutic effects by using C-ion RT with concurrent chemotherapy.

<b><i>Objectives:</i></b> Soft tissue metastasis (STM) is an uncommon condition in carcinoma. Although various case series related to STM have been reported, few reports have examined prognostic factors. This study aimed to evaluate the characteristics of STM and the factors affecting its prognosis. <b><i>Materials and Methods:</i></b> Patients with STM from carcinoma were retrospectively studied. The patients’ information, including age, sex, primary tumor, metastasis location, size of the metastatic tumor, presence of pain, histological classification, history of primary tumor treatment, and other metastasis at diagnosis of STM were collected and associated with prognosis. <b><i>Results:</i></b> Overall, 16 patients with a mean age of 68.7 years were evaluated. The overall survival rate was not significantly different between lung cancer and non-lung cancer patients. The overall survival rate was significantly better in patients undergoing definitive treatment for the primary tumor than in those without history of treatment (<i>p</i> = 0.046). The overall survival rate of STM patients with no metastasis was significantly better than those with other metastasis at the diagnosis of STM (<i>p</i> = 0.041). On multivariate analysis, no history of primary tumor treatment and STM without pain were risk factors for prognosis (<i>p</i> = 0.0340 and 0.0474, respectively). None of the patients who developed STM under the skin experienced pain, while 92.3% of the patients who developed STM in the deep layer had pain. <b><i>Conclusion:</i></b> The risk factors for poor diagnosis of STM were no past treatment of the primary tumor and absence of pain. STM in the deep layer is prone to pain.

Aim: PD-1 inhibitors have a leading role among immunotherapy while its efficacy on colorectal cancer (CRC) patients did not reach consensus and the small sample size remains as a limitation. Therefore, we undertook a meta-analysis on the effects of the monotherapy anti-PD-1 inhibitors in treating metastatic colorectal cancer (mCRC). Materials & methods: We searched databases to identify studies on efficacy of anti-PD-1 inhibitor on CRC. Objectives were objective response rate, progression-free survival rate, disease control rate and overall survival rate with their 95% CI. Results: The overall survival rate at 1-year was 64.2% (95% CI: 0.46–0.83). Disease control rate was 56.5% (CI: 0.27–0.86) and the objective response rate as 19.7% (CI: 0.08–0.32). The 1-year-progression-free survival rate was 38.4% (CI: 0.12–0.66). Sensitivity analysis and subgroup analysis were also conducted. Conclusion: The monotherapy anti-PD-1 inhibitors are effective in treating mCRC and could be a new option for dMMR mCRC patient in first-line treatment.
