Uterine myomas are heterogeneous tumors in composition, size, location, and number; variation in any of these factors could possibly alter the effect on a woman's fertility status. The effect of myomas on fertility has been the subject of many studies. However, a definitive answer is still missing. The location and size of the myomas are the two parameters that influence the success of a future pregnancy. Subserosal myomas seem to have little effect on reproductive outcome. Myomas that compress the uterine cavity with an intramural portion and submucosal myomas significantly reduce pregnancy rates, and should be removed before assisted reproductive techniques are performed. Patients with intramural myomas also may have a poorer reproductive outcome, but the lacks of quality evaluations make this conclusion tenuous at best. Removal of myomas with an intra-cavitary component seems to be of benefit. However there are as yet no data to support myomectomy in the treatment of intramural myomas to improve fertility outcomes. Treatment modality for myomas located at intramural sites should be determined according to clinical status of the patient and doctor's experience.

Background: Lymph node metastasis is commonly reported in thoracic esophageal cancer, even in the early esophageal cancer which may be localized only in the mucosa or within the submucosal layer. Although lymph node metastasis greatly influence long-term outcome and cure of the disease, endoscopic mucosal resection or photodynamic therapy without lymph node dissection is widely attempted. The investigation of the pattern of lymph node metastasis and results of surgical resection of superficial esophageal cancer is needed. Material and Method: Pattern of lymph node metastsis and depth of tumor invasion were studied retrospectively from 44 patients with early esophageal cancer who underwent radical resection of the tumor from December, 1995 to August, 2001. Result: Lymph node metastasis was found in 10 patients (22.7%) out of total of 44 patients. Lymph node metastasis was found in 0% (0 of 3), 0% (0 of 4), 50% (2 of 4), and 24.24% (8 of 33) of tumors that invaded the intraepitherium, lamina propria, muscularis mucosa, and submucosa respectively. Anatomically distant lymph node metastases were found more frequently in recurrent laryngeal nerve node(5 cases of 10 patients) and in intraperitoneal node (8 cases of 10). than intrathoracic node (3 cases of 10). There was no operative mortality, however, there were 1 hospital death in patient with lamina propria cancer, 1 late death in patient with submucosal cancer. Three-year survival rates (except hospital death) were 100% in mucosal cancer and 97.0% in submucosal cancer (p>0.05), and 100% in the node negative group and 90.0% in the node positive group (p>0.05). Conclusion: The survival rate of superficial esophageal cancer patient who was recieved operative resection was excellent. But, lymph node metastasis were found in superficial esophageal cancer, even in esophageal cancer limited to the muscularis mucosa. Systemic lymph node dissection which includes recurrent laryngeal nerve nodes and intraperitoneal nodes was recommended for favorable outcome in superficial esophageal cancer.

This is a report of gastric metastases secondary from a primary small cell carcinoma of the lung in two men. Blood-borne metastatic involvement of the stomach by cancer is a rare entity. According to the reports in the literature the prevalence of metastasis to the stomach occurs in 0.4% and the most common cell type of the primary lung carcinoma is large cell type(3.7%) followed by adenocarcinoma(2.4%), small cell carcinoma(1.7%) and squamous cell carcinoma(0.7%). The most common tumors that spread to the stomach through the blood stream are malignant melanoma, breast carcinoma and lung carcinoma. Most of the gastrointestinal tract metastases had no specific symptoms because of its submucosal involvement. The prognosis was poor and the mean survival period from the onset of symptoms was 49 days. The first patient was a 56-year-old man who had primary lung carcinoma with brain metastasis. Gastroscopic findings showed two elevated mass lesions in the anterior wall of the mid body with central ulcer and the posterior wall of the fundus with intact surface mucosa. Pathologic examination of stomach tissue revealed small cell type tumor cells infiltrate in the stomach wall segmentally without destruction of the glands. The second patient was a 67-year-old man who had no other evidence of the distant metastasis. Gastroscopic findings showed a huge, oval shaped, ulcerofungating mass with deep penetrating central ulcer coated with dirty exudate in the anterior wall from mid to upper body of the stomach, and thickened elevated rugal folds in the posterior wall of the fundus. Pathologic examination of stomach tissues revealed the small cell type tumor cells showing small smudged nucleus infiltrate into the mucosa of the stomach and the architecture of mucosa intact. We report the two cases of metastatic gastric cancer from the primary small cell lung carcinoma with the literature review.

Purpose: Expanded indications for endoscopic submucosal dissection (ESD) in early gastric cancer (EGC) remain controversial due to the potential risk of undertreatment after adequate lymph node dissection (LND). Regional LND (RLND) is a novel technique used for limited lymphadenectomy to avoid gastrectomy. This study established the safety and effectiveness of RNLD as an additional treatment option after ESD for expanded indications. Materials and Methods: A total of 69 patients who met the expanded indications for ESD were prospectively enrolled from 2014 to 2017. The tumors were localized using intraoperative esophagogastroduodenoscopy (EGD) before RLND. All patients underwent RLND first, followed by conventional radical gastrectomy with LND. The locations of the preoperative and intraoperative EGD were compared. Pathologic findings of the primary lesion and the RLND status were analyzed. Results: The concordance rates of tumor location between the preoperative and intraoperative EGD were 79.7%, 76.8%, and 63.8% according to the longitudinal, circumferential, and regional locations, respectively. Of the 4 patients (5.7%) with metastatic LNs, 3 were pathologically classified as beyond the expanded indication for ESD and 1 had a single LN metastasis in the regional lymph node. Conclusions: RLND is a safe additional option for the treatment of EGC in patients meeting expanded indications after ESD.
