A Case of Synchronous Lung Squamous Cell Carcinoma and Diffuse Large B-cell Lymphoma / 대한내과학회지

A 65-year-old male was referred to our hospital for evaluation of a right pleural effusion. Thoracic computed tomography (CT) revealed a huge central mass with right hilar and subcarinal lymph node conglomerates. An endobronchial mass was incidentally found in the right upper lobe bronchus, and endobronchial ultrasound-guided transbronchial needle biopsy of the mediastinal lymph nodes was thus also performed at the time of bronchoscopy. The two biopsies revealed squamous cell carcinoma and diffuse large B-cell lymphoma (DLBCL), respectively. As the pathology of the mediastinal lymph nodes was unknown, the lung cancer could not be accurately staged. Thus, we treated the DLBCL; follow-up positron emission tomography/CT after two cycles of chemotherapy showed that the conglomerate mass had disappeared but the right upper lobe lesion remained. Lung cancer staging thus became more accurate and radical treatment could be considered. To the best of our knowledge, this is the first report of a co-existing squamous cell carcinoma of the lung and DLBCL of the intrapulmonary lymph nodes.

Quadruple Metachronous Primary Malignant Neoplasm in the Head and Neck and Digestive Tract / 대한내과학회지

Multiple primary cancers, i.e., the occurrence of multiple malignant neoplasms in a single patient, were first reported by Billorth in 1889. The incidence is low but increasing gradually due to developments in cancer diagnosis, early detection, and prolongation of life. In Korea, double primary cancers are occasionally reported. However, the simultaneous presence of four primary cancers in a single patient is rare. Recently, we experienced the case of a 68-year-old male diagnosed with quadruple primary cancers involving the esophagus, tonsils, liver and buccal mucosa. Here, we report this very rare case of four metachronous primary neoplasms and provide a brief review of the related literature.

Incidence of Post-transplant Malignancy after Renal Transplantation: Single Center Analysis / 대한이식학회지

BACKGROUND: Immunosuppression after kidney transplantation is associated with increased risk of malignancy, which has become the second most common cause of death among kidney transplant recipients. In this review, we report the incidence of malignancies after kidney transplantation in a single center and evaluate the incidence, characteristics, relationship to immunosuppressive drugs and discuss what clinicians must consider during a follow-up of patients after kidney transplantation. METHODS: Between May 1978 and September 2013, a total of 748 kidney transplant patients who were able to undergo a follow-up process through electronic medical records were enrolled in this retrospective cohort study to determine the potential incidence and types of malignancy that may occur after kidney transplantation and the associated impact on patients and graft survival. RESULTS: Among 748 patients, 63 cases of malignancy appeared in 54 patients (7.2%). Gastrointestinal cancer (12 cases, 19%) and post-transplant lymphoproliferative disorder (12 cases, 19%) were the two most common types of malignancy. The second most common type of malignancy was urinary tract malignancy in 10 patients. Two different types of malignancy were diagnosed in nine patients during our follow-up. The overall graft survival in malignancy patients was better, which may mean that malignancy did not affect the overall graft loss. CONCLUSIONS: Clinicians should be aware of the incidence of malignancy in transplant patients and perform routine examinations for early detection of malignancy.

A Case of Multiple Primary Cancer with Follicular Lymphoma

The incidence of multiple primary cancer (MPC) is low but has been reported occasionally. Although follicular lymphoma is rare in Korea, the incidence is reported to be gradually increasing. We report a case of synchronous and metachronous MPC consisting of esophagus (squamous cell carcinoma), stomach (adenocarcinoma), and ampulla of Vater (extranodal follicular lymphoma grade 1) in a patient diagnosed as follicular lymphoma (grade 3a) six years ago. In a complicated case like ours, concurrent therapeutic control of synchronous MPC and metachronous hematological malignancy is challenging; meticulous examination and prioritized target therapy are essential for patients' survival.

Clinical Characteristics of Colorectal Cancer Patients With a Second Primary Cancer

PURPOSE: The incidence of colorectal cancer is increasing due to a westernized dietary lifestyle, and improvements in treatment and diagnostic tools have resulted in more patients being confirmed of having multiple primary cancers. However, studies regarding multiple primary cancers are insufficient. In this study, the clinical aspects of patients with primary multiple cancers, including colorectal cancers, were investigated, and the results were compared to those of patients with primary colorectal cancer only. METHODS: Seven hundred eighteen patients who received surgery for colorectal cancer between March 2003 and September 2012 in CHA Medical Center were enrolled. A retrograde cohort was done for comparison of the two groups: those with and those without multiple primary cancer. The analysis was done according to sex, age, tumor location, tumor size, metastatic regional lymph-node number, vascular/lymphatic microinvasion, staging, tumor markers, microsatellite instability, and C/T subgroup of polymorphism in methylenetetrahydrofolate reductase. RESULTS: Of the 718 subjects, 33 (4.6%) had multiple primary cancers: 12 (36.4%) synchronous and 21 (63.6%) metachronous. The malignancy most frequently accompanying colorectal cancer was gastric cancer, followed by thyroid, prostate, and esophageal malignancies in that order. In the comparison between groups, mean age, tumor location, and microsatellite instability showed statistically significant differences; others parameters did not. CONCLUSION: The incidence of multiple primary cancers, including colorectal cancer, is increasing. Therefore, defining the characteristics of patients with multiple primary cancers is crucial, and those characteristics need to be acknowledged in the follow-up of colorectal cancer patients.

Cáncer primario múltiple sincrónico: a propósito de un caso / Synchronous multiple primary cancer: report of a case

Los tumores malignos primarios múltiples sincrónicos son relativamente inusuales, aunque el número de pacientes diagnosticados con tumores primarios múltiples se está incrementando, dado al desarrollo de procedimientos diagnósticos más sofisticados, invasivos o no invasivos, y el incremento del número de pacientes ancianos. Los canceres sincrónicos al triple fueron reportados en solo el 1,2-1,9% de todos los canceres primarios. Los órganos digestivos son el sitio más común para tumores malignos primarios múltiples y también es el sitio usual del tumor primario. Nosotros describiremos los síntomas, diagnostico y tratamiento de un paciente masculino de 65 años con tumores gástricos malignos múltiples sincrónicos asociado a un cáncer de esófago.

Synchronous multiple primary malignant tumors are relatively unusual, although the number of patients diagnosed with multiple primary tumors is increasing due to development of more sophisticated invasive and non-invasive diagnostic tools and an increase in the number of elderly patients. Synchronous triple cancers were reported in only 1.2-1,9% of all primary cancers. Digestives organs are the most common tumor site for multiple primary malignant tumors and also the usual site for primary tumors. We will describe the symptoms, diagnosis and treatment of a 65 year-old male patient with synchronous gastric malignant tumors associated with esophageal cancer.

Endoscopic Submucosal Dissection of Early Gastric Cancer That Occurred in a Patient with Chronic Myelogenous Leukemia / 대한소화기내시경학회지

Synchronous double malignancies of early gastric cancer and chronic myelogenous leukemia (CML) are very rare. There are few reports regarding the effect of the CML or imatinib on stomach cancer, and it is difficult to make a decision for the proper timing of treatment for early gastric cancer (EGC) in a patient with CML. A 56-year-old man was diagnosed with early gastric cancer. During the evaluation of his disease, he was also diagnosed as having Philadelphia chromosome positive chronic myleogenous leukemia. He started to take 400 mg of imatinib per day. Two weeks later, he underwent endoscopic submucosal dissection (ESD) for the early gastric cancer. Although there was a bleeding complication, complete resection was successfully performed. ESD is an effective treatment modality for EGC in CML patients, but physicians should keep a watchful eye for bleeding complications after the procedure. Further studies and more experience are needed to determine the proper timing of treatment for these patients.

A case report of quadruple cancer in a single patient including the breast, rectum, ovary, and endometrium / 부인종양

Multiple primary cancer is defined as the multiple occurrence of malignant neoplasms in the same individual. Due to the development of new diagnostic techniques and the rise in long-term survival of cancer, reports of multiple primary cancers have gradually increased. Herein, we describe the case of a 68-year-old female patient with quadruple primary cancer of the breast, rectum, ovary, and endometrium. For its great rarity, we report this case with a review of the literature.

A case of Combined Resection for Synchronous Primary Carcinoma of Gallbladder and Duodenum

PURPOSE: The incidence of multiple primary malignant tumor has ranged from 0.7% to 11% in the medical literature. Various organs in the digestive system are the sites of multiple primary cancer (MPC). MPC may be synchronous or metachronous depending on the interval between their diagnosis. To the best of our knowledge, there are only rare reports of resected cases of synchronous primary carcinomas that developed in the GB and duodenum. METHODS: We present here a patient who underwent an operation for synchronous primary carcinomas of the GB and duodenum. A 51-year-old female was admitted for postprandial abdominal discomfort. CT scan and MRI of the abdomen showed a 3 x 2 cm sized heterogenously enhancing mass in the GB and a 3.7 x 2.7 cm sized hetrogenously enhancing mass in the 2nd portion of the duodeum. The laboratory findings, including the tumor markers, were non-specific. An elective operation was done under the impression of combined GB cancer and cancer in the 2nd portion of the deuodenum. On the operative findings, there was a 3 x 2.5 cm sized mass in the GB and a 5 x 4 cm sized duodenal mass with near complete luminal obstruction 3 cm distal from the pyloric ring. Radical cholecystectomy with wedge resection of the liver bed and Whipple's operation was performed. RESULTS: On microscopic examination, the GB mass was well differentiated adenocarcinoma and the duodenal mass was moderately differentiated adenocarcinoma, and one lymph node (a lymph node along the common hepatic artery) among the 18 dissected lymph nodes was invaded by tumor cells. The microscopic findings showed that the GB mass and duodenal mass were synchronous primary carcinomas. The patient recovered uneventfully and is alive and doing well without evidence of recurrence at 21-months of follow up evaluation. CONCLUSIONS: We report here on a case of combined curative resection for synchronous primary carcinomas of the gallbladder and duodenum.

Clinical Characteristics of Multiple Primary Cancer in Breast Cancer Patients / 한국유방암학회지

PURPOSE: Since 2001, breast cancer has been the most common type of cancer observed in Korean women. Due to improved screening and treatment, multiple primary cancer (MPC) in association with breast cancer has been more prevalent. However, there is a lack of information regarding MPC in Korea. Therefore, this study was conducted to provide an overview of the clinical characteristics of MPC that occurs in association with breast cancer. METHODS: We retrospectively investigated 149 patients with MPC, including breast cancer patients, who were treated between July 1989 and December 2005 at the Breast clinic in Asan Medical Center. Patients with contra-lateral breast cancer as well as patients that experienced a recurrence of breast cancer were excluded from this study. We studied the clinical characteristics of patients including the mean age, stage of disease, hormone receptor status, cause of death, common cancers that were combined with breast cancer, the time interval between the onset of breast cancer and other cancers, and mean survival. We considered the cancer to be synchronous if a second cancer has been diagnosed at least six months before the diagnosis of an initial primary cancer, however, other forms of cancer were considered to be metachronous. RESULTS: Of 149 patients, 146 patients were female (98.0%) and 3 were male (2.0%). The mean age of the study group was 51.5, which is higher than the mean age of 47.3 that was observed in breast cancer patients at our hospital during the same period (p<0.001). Forty-four of the patients evaluated in this study had synchronous cases of cancer, whereas the remaining 88 patients had metachronous MPC. In metachronous cancers, the average time between diagnosis with the primary cancer and the secondary cancer was 5.2 yr. The most common cancer found to be combined with breast cancer included cancer of the thyroid (45, 29.2%), cervix and uterus (28, 18.2%), stomach (19, 12.3%), colon and rectum (15, 9.7%), ovary (11, 7.1%) and lung (9, 5.8%). CONCLUSION: Thyroid cancer is the cancer most commonly associated with breast cancer, and the mean age of MPC patients was higher than that of patients who only had breast cancer. Due to the improved survival length and treatment, MPC associated with breast cancer is now a greater concern.

Double Primary Cancers Developed at the Colorectum and Stomach

PURPOSE: Stomach cancer is the most prevalent extracolonic malignancy of the many primary cancers that occur together with colorectal cancer in Koreans. The purpose of this study was to evaluate the characteristics of patients who present with double primary cancer of the stomach and colorectum. METHODS: From Sep. 1994 to Dec. 2004, in 4,305 patients were diagnosed with colorectal cancer. Among these patients, 51 patients were diagnosed synchronously or metachronously as also having stomach cancer. The mean age these patients was 60.8 years and the median follow up duration was 31.0 months. RESULTS: The incidence of double primary cancer of the stomach and colorectum was 1.2% of the total colorecal cancer patients and they were 0.6% of the total stomach cancer patients. There were 17 (33.3%) metachronous cases and 34 (66.7%) synchronous cases. For the metachronous cases, the mean interval was 15 months (12~98) and detection methods were postoperative CT, symptom of second a cancer, and routine endoscopic examination. In synchronous cases, second cancer was detected by routine endoscopic examination, preoperative radiologic evaluation, and intraoperative exploration. Intraoperatively the detected cancers were all colorectal cancer during the operation for stomach cancer. The stage of the colorectal cancer was higher than that of the stomach cancer in 30 cases. Local or systemic recurrences were seen in 9 cases (17.6%), and 7 cases were recurrence of colorectal cancer. The 5-year disease free survival rates was 55.8%. CONCLUSION: The incidence of cancer arising from colorectum and stomach has been reported to be increasing. Careful attention should always be paid to the possible presence of a second cancer in preoperative or postoperative evaluation of cancer patients.

Synchronous double cancer of rectal non-Hodgkin lymphoma and lung cancer: 1 case report / 대한내과학회지

Colorectal lymphomas constitute 10~20% of gastrointestinal lymphomas and arerelatively rarer than lymphomas which involve stomach or small intestine. Rectal lymphomas compose fewer than 1% of malignant rectal tumors. Although there are several case reports and reviews about non-Hodgkin lymphoma associated with primary lung cancer in Korea, the case of synchronous double cancer of rectal lymphoma and primary lung cancer was not reported yet. We report a case of synchronous double primary cancer of rectal lymphoma and squamous cell carcinoma of lung in 71-year-old man who presented with incidental right upper lung mass.

Metachronous Triple Primary Cancers

Multiple primary cancer is defined as the multiple occurrence of malignant neoplasms in the same individual. According to the development of new diagnostic techniques and the increase in long-term survivals, reports of multiple primary cancer have been gradually increasing among patients treated for initial cancers. Since Theodor Billroth reported the first three cases of multiple primary cancer in 1889, there have been many reports of multiple primary cancer, with an incidence range in Korea of 0.35~1.84%. In Korea, there have been a few reported cases of triple cancer. Herein, three recently experienced cases of metachronous triple primary cancer are reported.

Study of Combined Multiple Primary Cancer in Gastric Cancer Patients

PURPOSE: With recent advances in diagnostic techniques, and the increase in early cancers, the number of multiple primary cancers appears to be increasing. The recurrence of gastric cancer, after a radical operation, is the main cause of death, but the interest in the development of multiple cancers is also increasing. The purpose of this study was to evaluate the characteristics of gastric cancer with those of other combined organ cancers. METHODS: A comparison of 66 patients with multiple organ cancers, combined with gastric cancer, was made with 2, 444 of gastric cancer patients, who underwent operation at the Department of Surgery, Chonnam National University Hospital, between Jan. 1982 and Dec. 2000. RESULTS: The incidence of multiple cancers was 2.6% of the total gastric cancer patients. Of these 25.8% were detected at the same time as the gastric cancer, and 74.5% were detected before, or after, the operation for the gastric cancer. The sex ratio was 2: 1 with gastric cancer only, and 1.4: 1 with the multiple organ cancers, with a male predominance. The mean age of the multiple organ cancer patients was 57.1 years old (male: 59.4 years, female: 54.1 years), which showed no statistical difference to single gastric cancer. The location of the multiple cancers was common in the digestive tract, especially the colon. In terms of the histological types of gastric cancer, the incidence was highest in the poorly- differentiated, followed by the moderate and the well- differentiated cancers, respectively. However, the incidence of the poorly-differentiated type, in the multiple organ cancers, was lower than that in the single gastric cancer patients. There was no difference in stage between the multiple organ and gastric cancers. The 5-year survival rates were 51.6 and 50.6% in the gastric and multiple organ cancers, respectively, but with no statistical difference. The prognosis of multiple cancers wsa no different to that of single gastric cancer. CONCLUSION: This study suggests that more active treatment is needed in the treatment of gastric cancer, irrespective of involvement with other organ cancers.

A Case of Multiple Primary Malignancy / 대한산부인과학회잡지

Multiple primary cancer means that more than two cancers are independently developed in one individual. The frequency of multiple primary neoplasm is increasing as a result of the lengthening average lifetime, progress in cancer screening technique, and improved cancer therapy. Gynecologic malignancies are especially prone to associated with primary neoplasms elsewhere. The frequency of multiple primary cancers was significantly higher in patients with uterine corpus cancer than in those suffering from cervical cancer. This case has different cell types of cancer in uterine cervix, thyroid and colon simultaneously. So, we report the case with a brief review of literatures.

Primary Duodenal Cancer Combined with Gastric Cancer after Treatment of Cervical Cancer -triple primary cancer

Multiple primary tumors are defined as cases involving primary malignant tumors of different histologic origins in one person. The absolute number of reported cases of double primary malignant tumors has increased in recent years diagnostic procedures. Primary adenocarcinoma of duodenum is a rare disease and represents less than 0.5% of all gastrointestinal malignancies. Therefore, synchronous multiple primary cancers of the stomach and duodenum are very rare. Recently, we experienced a case of triple primary malignant tumors of different site originating from the stomach, duodenum and cervix in 71- year-old woman. She had had radiation therapy and chemotherapy for squamous cell carcinoma of the uterine cervix 8 years previously. We performed subtotal gastrectomy and pancreaticoduodenectomy with radical lymph node dissection. She remained healthy without any evidence of recurrence 12 months after the operation.

Multiple Primary Malignant Tumors in Patients with Gastric Cancer

PURPOSE: Because of an improving gastric cancer detection program and treatment methods, we can expect improved survival of patients with gastric cancer. Given the longer survival times, the chance of an occurrence of multiple primary malignant tumors other than stomach is increased in the same patients. The purpose of this study is to analyze the clinical characteristrics and the survival of patients with gastric cancer and other malignancies. MATENRIALS AND METHODS: A retrospective study of 3669 patients with gastric cancer observed at our department between January 1994 to December 2002 was conducted. Associated tumors were diagnosed using the Warren and Gates criteria, and included tumors that were not considered to be a metastasis, invasion, or recurrence of the gastric cancer. RESULTS: Of all 3669 patients, 2.07% (n=76) had primary tumors other than gastric cancer, 63% of which were synchronous (n=48) and 37% metachronous (n=28). The mean age of the study group was 64.9 (65.5 in males, 61.8 in females), and the male-to-female ratio was 4.8 : 1. The most common cancer associated with gastric cancer was a hepatocellular carcinoma (23.7%), followed by colorectal cancer (17.1%), esophageal cancer (10.5%), breast cancer (6.6%). Of the 45 patients who had undergone a resection, 14 were in stage I, 12 in stage II, 13 in stage III, and 6 in stage IV. No statistically significant differences were found between the synchronous and the metachronous groups with regard to age, sex ratio, differentiation, and stage. The 5-year survival rates of the metachronous and the resected patients were significantly higher than those of the synchronous and the non resected patients, respectively. CONCLUSION: Due to increasing length of the follow-up period for patients with gastric cancer, another malignancy may develop in other organs. Therefore, physicians should pay attention to detect other cancers early in these patients, and a surgical resection is recommended as the treatment of choice in the management of multiple primary cancer associated with gastric cancer.
