ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to perform dosimetric analysis of radiotherapy (RT) plans with or without elective nodal irradiation (ENI) and estimate whether the increase in mean doses (MDs) in the heart and lungs with ENI may lead to late side effects that may surpass the benefits of treatment. METHODS: The dosimetric analysis of 30 treatment plans was done with or without ENI. The planning and dose-volume histograms were analyzed, and the impact on the mortality of cardiovascular and lung cancer was estimated based on the correlation of the dosimetric data with data from population studies. RESULTS: RT with ENI increased the doses in the lungs and heterogeneity in the plans compared to breast-exclusive RT. When the increase in MDs is correlated with the increase of late side-effect risks, the most important effect of ENI is the increased risk of lung cancer, especially in patients who smoke (average increase in absolute risk=1.38%). The increase in the absolute risk of cardiovascular diseases was below 0.1% in the all the situations analyzed. CONCLUSIONS: ENI increases the heterogeneity and the doses at the lungs. When recommending ENI, the risks and benefits must be taken into account, considering the oncology factors and the plan of each patient. Special attention must be given to patients who smoke as ENI may lead to a significant increase in MD in the lung and the increased risk of radiation-induced lung cancer may surpass the benefits from this treatment.

ABSTRACT

Circulating tumor cells (CTC) are tumor cells that escape from the primary or metastatic tumor into the circulatory system, and closely related to cancer metastasis. Since the samples can be obtained through simple and minimally invasive blood sampling operations, CTCs have a great clinical potential. PCa is one of the most common malignant tumors in men. In recent years, many scholars have conducted studies as to whether CTC technology can be used for the diagnosis and treatment of PCa, as well as for more accurate prediction of the risk of progression. This article summarizes the advances in researches relating CTC technology and the diagnosis and treatment of PCa. CTC detection has been developed from simple counting to phenotypic classification, and even to its combination with the determination of the expressions of specific genes (such as AR, AR-V7, etc.) and single-cell sequencing. Some reports showed that CTC technology has a certain significance in the early diagnosis of PCa, but its main value is demonstrated in drug sensitivity and prognosis evaluation in the late stage of the malignancy. The standardized detection methods and reference values of CTCs in PCa will be important research orientations in the near future.

ABSTRACT

Objective To investigate the impact of prior non-pancreatic cancer on the survival outcomes of patients with localized pancreatic neuroendocrine tumors (PanNETs). Methods We reviewed the Surveillance, Epidemiology, and End Results database and selected patients with localized PanNETs diagnosed between 1973 and 2015. We divided the patients into two groups according to the presence or absence of prior non-pancreatic malignancy. Before and after propensity score matching, we compared the clinicopathological characteristics and studied the overall survival and cancer-specific survival. Results A total of 357 (12.9%) of 2778 patients with localized PanNETs had prior cancer. A total of 1211 cases with only a localized PanNET and 133 cases with a localized PanNET and prior cancer had complete data and met the inclusion criteria of the current study. Patients with prior cancer were associated with advanced age (>65 years, 57.9% prior cancer

ABSTRACT

BACKGROUND@#With the wide application of endoscopic submucosal dissection (ESD) for early gastric neoplasms, metachronous gastric neoplasms (MGN) have gradually become a concern. This study aimed to analyze the characteristics of MGN and evaluate the treatment and follow-up outcomes of MGN patients.@*METHODS@#A total of 814 patients were retrospectively enrolled. All these patients were treated by ESD for early gastric cancer or gastric dysplasia between November 2006 and September 2019 at The First Medical Center of Chinese People's Liberation Army General Hospital. The risk factors for MGN were analyzed using Cox hazard proportional model. Moreover, the cumulative incidence, the correlation of initial lesions and MGN lesions, and the treatment and follow-up outcomes of MGN patients were analyzed.@*RESULTS@#A total of 4.5% (37/814) of patients had MGN after curative ESD. The 3-, 5-, and 7-year cumulative incidences of MGN were 3.5%, 5.1%, and 6.9%, respectively, and ultimately reaching a plateau of 11.3% at 99 months after ESD. There was no significant correlation between initial lesions and MGN lesions in terms of gross type (P = 0.178), location (long axis: P = 0.470; short axis: P = 0.125), and histological type (P = 0.832). Cox multivariable analysis found that initial multiplicity was the only independent risk factor of MGN (hazard ratio: 4.3, 95% confidence interval: 2.0-9.4, P < 0.001). Seventy-three percent of patients with MGN were treated by endoscopic resection. During follow-up, two patients with MGN died of gastric cancer with lymph node metastasis. The disease-specific survival rate was significantly lower in patients with MGN than that in patients without MGN (94.6% vs. 99.6%, P = 0.006).@*CONCLUSIONS@#The MGN rate gradually increased with follow-up time within 99 months after curative gastric ESD. Thus, regular and long-term surveillance endoscopy may be helpful, especially for patients with initial multiple neoplasms.

ABSTRACT

RESUMEN Las metástasis pancreáticas por carcinoma renal de células claras son excepcionales; en general, se presentan como tumores asintomáticos de diagnóstico incidental. Caso clínico: hombre de 61 años, nefrectomizado hace 10 años; durante el seguimiento se detecta una masa pancreática distal de 3 cm, hipervascular. Se realiza pancreatectomía corporocaudal laparoscópica, confirmándose la presencia de una metástasis de carcinoma renal. Las metástasis pancreáticas del carcinoma renal suelen apare cer en forma asintomática y metacrónica. La resección quirúrgica logra buenos resultados oncológicos y debe intentarse siempre que sea posible. En este caso destacamos que se pudo realizar una exéresis radical mediante abordaje mínimamente invasivo.


ABSTRACT Pancreatic metastases from clear cell renal carcinoma are very rare, and generally present as incidental asymptomatic tumors. Case report: a 61-year-old male patient with a history of nephrectomy 10 years before presented a 3-cm hypervascular mass in the distal pancreas during follow-up. A laparoscopic distal pancreatectomy was performed, confirming the presence of metastasis from a renal cell carci noma. Pancreatic metastases from renal cell carcinoma are usually metachronous and asymptomatic. Surgical resection is associated with favorable oncological results and, if possible, should be attempted. In our case, a successful oncological resection could be performed through a minimally invasive ap proach.

ABSTRACT

Hypopharyngeal cancer and esophageal cancer often occur synchronously or metachronously. Timely screening, diagnosis and individual treatment are important to improve the prognosis of patients. At present, there is no clinical guideline or consensus in this cross-cutting area in China, and there is a need of consistent diagnosis and treatment recommendation for these patients. Under the sponsorship of the Committee of Esophageal Cancer in China Anti-Cancer Association, the Chinese Working Group on Cooperative Diagnosis and Treatment of Hypopharyngeal and Esophageal Cancer was established by domestic experts in the fields of otolaryngology head and neck surgery, radiation oncology, and gastrointestinal endoscopy. This consensus document on multiple primary cancers (simultaneous or metachronous) of the hypopharynx and esophagus was developed through literature review, collective experience and expert discussions. The goals of the consensus include: (1) raising concern for this cross-cutting field; (2) establishing a preliminary clinical diagnosis and treatment recommendation; (3) preparing for the establishment of future high-level guidelines through standardized clinical practice.

ABSTRACT

Introducción: La metástasis de origen desconocido es una entidad clínica relativamente común, que representa del 5% de todos los cánceres invasivos. La búsqueda del origen primario puede resultar desafiante por un patrón atípico metastásico, no obstante el adenocarcinoma y carcinomas indiferenciados representan un 75% siendo el adenocarcinoma el más complicado de determinar su sitio primario ya que sus características citológicas/histológicas generalmente no son específicas. Por esta razón surge la necesidad identificar el origen primario de las lesiones metastásica de origen desconocido en pacientes con y sin antecedentes oncológicos personales, el sexo y edad de mayor prevalencia. Métodos: Investigación observacional descriptiva, retrospectiva tomándose como universo de 100 pacientes con diagnóstico histopatológico de Carcinoma/Adenocarcinoma metastásico en el departamento de Anatomía patológica del Instituto Oncológico Nacional "Dr. Juan Tanca Marengo"­ Solca-Guayaquil en el periodo 2013-2015, con y sin antecedentes oncológicos personales. Resultados: Se obtuvo una muestra de 91 pacientes, donde la localización metastásica más frecuente fue en los ganglios cervicales (27%), seguida del hígado (13%), hueso y epiplón (9%). Además, en 69 de ellos pudo ser posible la identificación del origen primario de la lesión metastásica. Conclusión: La topografía metastásica de neoplasia primaria desconocida tales como los ganglios cervicales y el hígado son los lugares de notable predominio, siendo el ganglio cervical el lugar de biopsia por excelencia debido a su mayor accesibilidad. La metástasis de origen desconocido a pesar de ser más frecuente en el sexo femenino, tiene una gran incidencia en el grupo etario entre 61-70 años.


Introduction: The metastasis of unknown origin is clinical entity relatively common, which represents 5% of all invasive cancer. The research of the primary origin could be difficult because of its atypical pattern, instead that, the undifferentiated adenocarcinoma and carcinoma represents 75% , being adenocarcinoma the most complicated to diagnoses the primary origin because of their unspecific characteristic cytological/histological. For this reason is necessary to identify the primary origin of the metastatic lesion with unknown origin in patients with or without personal oncological background, sex and age with higher prevalence. Methods: Observational, descriptive- retrospective investigation that used the collection 100 patients with histopathologic diagnoses carcinoma/adenocarcinoma metastatic in the Anatomy Pathologic Department of ION-SOLCA period 2013-2015, with and without personal oncological background. Results: Sample of 91 patients, in 69 of them were the most frequently metastatic location was superior cervical ganglion (27%), liver (13%), bone and omentum (9%). Furthermore, 69 patients were possible to identify the primary origin of the metastatic lesion. Conclusion: The metastatic location of the neoplasm unknown primary such as superior cervical ganglion and liver are the places more common, being superior cervical ganglion with most accessibility for biopsies. The neoplasm unknown primary is more frequently in female sex and has a high incidence at the ages of 61-70 years.

ABSTRACT

BACKGROUND: The National Lung Screening Trial (NLST) and NELSON trial showed that low-dose chest computed tomography (LDCT) screening significantly reduced the mortality form lung cancer. Although cancer survivors are known to have high risk for second malignant neoplasm (SMN), the usefulness of LDCT screening for lung cancer in cancer survivors is not clear. METHODS: Between August 2016 and August 2017, 633 long-term colorectal cancer (CRC) survivors visited the survivorship clinic in Cancer Prevention Center, Yonsei Cancer Center, Seoul, Republic of Korea. We surveyed the smoking status and recommended LDCT screening to ever-smoking CRC survivors aged 55–80 years. The participants were classified into three risk groups: risk group 1 (RG1) who met the NLST criteria (Age 55–74 years, ≥ 30 pack-years of smoking, smoking cessation < 15 years); risk group 2 (RG2) who would not meet the NLST criteria but were at increased 6-year risk of lung cancer (PLCOM2012 ≥ 0.0151); risk group 3 (RG3) who did not meet any of the criteria above. RESULTS: Among 176 ever-smoking CRC survivors, 173 (98.3%) were male, 32 (18.2%) were current-smoker, and median age was 66 years (range, 55–79 years). We found 38 positive findings (non-calcified nodule ≥ 4 mm), 8 clinically significant findings, 66 minor abnormalities, and 64 negative findings on LDCT. Positive findings were identified in 15 of 79 (19.0%) of RG1, in 9 of 36 (25%) of RG2, and in 14 of 61 (23.0%) of RG3. Second primary lung cancers were found in 2 patients of RG2, and in 1 patient of RG3. SMN was most frequently found in RG2 (11 of 36 patients, 30.6%), compared with RG1 (12.7%) or RG3 (9.8%) (P = 0.016). CONCLUSIONS: LDCT screening for lung cancer in Korean CRC survivors is feasible. Well-designed clinical trial for defining high risk patients for lung cancer among CRC survivors is needed.

ABSTRACT

BACKGROUND: Cancer survivors are at a higher risk of primary cancer recurrence and development of second primary cancer. In both cases, early disease detection is crucial. This cross-sectional study assessed cancer screening participation rates according to cancer history. METHODS: Data were obtained from the 2010–2012 Korea National Health and Nutrition Examination Survey for 12,500 participants. Of these, 624 cancer survivors were enrolled in this study. Sampling weights were applied to maintain the representativeness of the Korean adult population. RESULTS: Overall 2-year cancer screening rates prior to the survey in male and female cancer survivors were 59.9% and 73.7%, respectively, while opportunistic cancer screening rates were 33.5% and 52.1%, respectively. The odds ratios (95% confidence interval) of the overall cancer screening among the cancer survivors, compared to others, were 1.16 (0.79–1.72) in male and 1.78 (1.20–2.63) in female participants, after the adjustment for confounding variables. The odds ratios (95% confidence interval) for opportunistic cancer screening and National Cancer Screening Program among cancer survivors were 1.56 (1.07–2.27) and 0.80 (0.53–1.21) in males and 2.05 (1.46–2.88) and 0.66 (0.46–0.95) in females. CONCLUSION: Female cancer survivors showed a higher rate of overall and opportunistic cancer screening than did the male cancer survivors. Further efforts are required to improve cancer screening among male cancer survivors.

ABSTRACT

Endoscopic submucosal dissection is widely accepted as standard treatment for early gastric cancer; however, long-term management of metachronous gastric cancer after endoscopic resection is an important issue that is gaining much attention. Several prospective and retrospective studies have reported that Helicobacter pylori (H. pylori) eradication can reduce the risk of metachronous gastric cancer after endoscopic resection. Although there is lack of sufficient data regarding this subject, a few studies have reported histologically proven improvement in atrophic gastritis and intestinal metaplasia following H. pylori eradication in patients undergoing endoscopic resection. Therefore, treatment for H. pylori eradication should be considered in this patient population to reduce the incidence of metachronous gastric cancer and improve long-term outcomes.(

ABSTRACT

Salivary gland tumors usually appear in solitary mass in single salivary gland. The coexistence of tumors with different histological types occurring within a unilateral parotid gland is an extremely rare event. We experienced a case which two different types of malignant tumors developed at different time points in same gland; metachronous tumors. The second tumor was excised widely and reconstruction was performed by free tissue transfer. Sensory and motor nerve to the left cheek appeared to be intact, and circulation was adequate. This rare case was presented in this article.

ABSTRACT

Advances in diagnosis and therapeutic technologies have brought increased life expectancy for most cancers, but paradoxically it also has increased the risk of second primary malignancies. Cancer survivors have a higher risk of developing cancer than the general population. This suggests that more studies are needed to develop screen and management programs for cancer survivors, especially patients with gastrointestinal cancers, which are the most common cancers in Korea.

ABSTRACT

PURPOSE: Dexrazoxane has been used as an effective cardioprotector against anthracycline cardiotoxicity. This study intended to analyze cardioprotective efficacy and secondary malignancy development, and elucidate risk factors for secondary malignancies in dexrazoxane-treated pediatric patients. MATERIALS AND METHODS: Data was collected from 15 hospitals in Korea. Patients who received any anthracyclines, and completed treatment without stem cell transplantation were included. For efficacy evaluation, the incidence of cardiac events and cardiac event-free survival rates were compared. Data about risk factors of secondary malignancies were collected. RESULTS: Data of total 1,453 cases were analyzed; dexrazoxane with every anthracyclines group (D group, 1,035 patients) and no dexrazoxane group (non-D group, 418 patients). Incidence of the reported cardiac events was not statistically different between two groups; however, the cardiac event-free survival rate of patients with more than 400 mg/m2 of anthracyclines was significantly higher in D group (91.2% vs. 80.1%, p=0.04). The 6-year cumulative incidence of secondary malignancy was not different between both groups after considering follow-up duration difference (non-D, 0.52%±0.37%; D, 0.60%±0.28%; p=0.55). The most influential risk factor for secondary malignancy was the duration of anthracycline administration according to multivariate analysis. CONCLUSION: Dexrazoxane had an efficacy in lowering cardiac event-free survival rates in patients with higher cumulative anthracyclines. As a result of multivariate analysis for assessing risk factors of secondary malignancy, the occurrence of secondary malignancy was not related to dexrazoxane administration.

ABSTRACT

BACKGROUND: Dietary patterns have a significant impact on prognosis, recurrence, and survival in patients with cancer. This study investigated dietary patterns using the Diet Quality Index-International (DQI-I) in cancer survivors compared to those in the general population without cancer.METHODS: Using the Korea National Health and Nutrition Examination Survey VI data, cancer survivors were defined as those diagnosed with cancer more than 1 year before the survey. The associations between possible predictors and the DQI-I score were examined using t-tests and analysis of variance. Adjusted multiple linear regression analysis was performed to compare the differences in DQI-I scores between cancer survivors and controls.RESULTS: In univariate analysis of 9,351 subjects (433 cancer survivors and 8,918 controls), age, sex, body mass index, marital status, education level, income, residential area, smoking status, and alcohol consumption were associated with the DQI-I score (each P-value < 0.05). After adjustment, cancer survivors showed higher DQI-I scores than the controls (67.40±8.90 vs. 65.50±9.40, P-value=0.007). In subgroup analysis, cancer survivors within 5 years after cancer diagnosis showed higher DQI-I scores than the controls (68.70±8.30 vs. 65.50±9.40, P-value=0.034), whereas those who survived beyond 5 years post-diagnosis did not show significant differences from the controls (66.70±9.20 vs. 65.50±9.40, P-value=0.063).CONCLUSION: Cancer survivors within 5 years of cancer diagnosis showed better dietary patterns than those in the general population. However, the differences were not observed after 5 years post-diagnosis. To reduce the risks of second primary cancer and mortality, targeted inventions for dietary habits are necessary for long-term survivors of cancer.
