Intramedullary spinal cord metastases are very rare. Patients with breast cancer as the primary source of intramedullary spinal cord metastases tend to do better than other types of cancer. We report the very unusual case of a woman with breast cancer who had two separate episodes of intramedullary spinal cord metastasis.

Gastrectomy with lymph node dissection remains the gold standard for curative treatment of gastric cancer. Dissection of splenic hilar lymph nodes has been included as a part of D2 lymph node dissection for proximal gastric cancer. Previously, pancreatico-splenectomy has been performed for dissecting splenic hilar lymph nodes, followed by pancreas-preserving splenectomy and spleen-preserving lymphadenectomy. However, the necessity of routine splenectomy or splenic hilar lymph node dissection has been under debate due to the increased morbidity caused by splenectomy and the poor prognostic feature of splenic hilar lymph node metastasis. In contrast, the relatively high incidence of splenic hilar lymph node metastasis, survival advantage, and therapeutic value of splenic hilar lymph node dissection in some patient subgroups, as well as the effective use of novel technologies, still supports the necessity and applicability of splenic hilar lymph node dissection. In this review, we aimed to evaluate the need for splenic hilar lymph node dissection and suggest the subgroup of patients with favorable outcomes.

Lymph node metastasis of thyroid cancer occurs to anterior compartment (level VI) and superior mediastinal lymph node (Level VII). In lateral neck, it occurs commonly in middle and lower jugular lymph node (level III, IV). And it can also metastasis to posterior neck lymph node (level V). Superior mediastinal lymph node metastasis of thyroid cancer requires superior mediastinal dissection with massive removal of peritracheal and periesophageal soft tissue. After superior mediastinal dissection, severe complication may occurs such as innominate artery rupture and tracheal necrosis. We describe a case of tracheal necrosis as a complication of superior mediastinal dissection and total thyroidectomy in thyroid cancer patient.

Although patients with breast cancer receive standard treatments, they often experience recurrence or metastasis of tumors. Therefore, patients seeking treatment with traditional Korean medicine (TKM) in addition to conventional treatment have increased. We present a case of 46-year-old female with recurring breast cancer. She underwent surgeries and various hormone therapies since being diagnosed in 2007. Upon follow-up examination, she had metastatic lesions on the lung and multiple bones in 2015 and 2016. She received TKM treatments from May 2017 with Aromasin and Afinitor. However, hepatic metastasis was found after two months, so she started Capecitabine with TKM. After about two months, the liver nodules disappeared and a seeding nodule in the right paracolic gutter was decreased. After two months, the tumor response was stable disease. Back pain due to bone metastasis was improved. We suggest that combination treatment of TKM and chemotherapy is a promising method for treating breast cancer.

Primary lung cancer can metastasize by a direct local extension, hematogenous dessemination, and lymphatic spread. However, it less commonly metastasizes via a transbronchial invasion. Approximately half of all patients with lung cancer have metastases at the initial presentation. Autopsy data showed that there are an average of 4.8 metastatic sites. The most common sites for metastases include the lymph nodes, liver, adrenal gland, bone, and brain. However clinically significant metastases isolated in the small bowel seldom occur. Here we report a case of lung cancer with a small bowel metastasis.

Objective: This study aimed to investigate the effects of BCRP expression on tumor recurrence, metastasis and treatment tolerability. Methods: A VX2 rabbit liver tumor model was established. Division was randomly into 4 groups: namely saline control group; A group, given hydration lipiodol; B group, Ad-p53; and C group, Ad-p53+hydration lipiodol. After the intervention, samples were collected to detect the BCRP, MMP-2, VEGF and PCNA. Results: The expression of BCRP, MMP-2, PCNA and VEGF in tumors in Group A had no significant difference when compared with the control group, while in B and C group, the values were significantly lower (P<0.05). BCRP positive expression in metastatic lesions significantly increased (P<0.05), and was correlated with MMP-2 ($X^2=6.172$, P=0.0131). Conclusions: BCRP may play an important role in mediating liver cancer multidrug resistance to chemotherapy, and may be correlated with tumor recurrence and metastasis, which leads to weakened treatment effect. Ad-P53 can down-regulate the expression of related genes, playing a role in multidrug resistance reversal and increased sensitivity in liver cancer treatment.

Uterine cervical cancer is one of the most common malignancies of the female genital tract. Most recurrent cases of uterine cervical cancer are diagnosed within two years after primary treatment, and late recurrence after a disease-free interval of more than five years is rare. In addition, peritoneal metastases usually present as multifocal discrete nodules in the peritoneal cavity with nodular or diffuse peritoneal thickening. Herein, we report an extremely rare case of late recurrent cervical cancer peritoneal metastasis with an unusual manifestation of a large, solitary necrotic mass in the right subphrenic space on contrast-enhanced CT.

Purpose : The purpose of this study was to determine the proper treatment time of stereotactic body radiation therapy for spine metastasis cancer by using the image guidance system of CyberKnife(Accuray Incorporated, USA) which is able to correct movements of patients during the treatment. Materials and Methods : Fifty seven spine metastasis cancer patients who have stereotactic body radiation therapy of CyberKnife participate, 8 of them with cervical spine cancer, 26 of them with thoracic spine cancer, and 23 of them with lumbar spine cancer. X-ray images acquired during the treatment were classified by treatment site. From the starting point of treatment, motion tendency of patients is analyzed in each section which is divided into every 5 minutes. Results : In case of cervical spine, there is sudden increase of variation in 15 minutes after the treatment starts in rotational direction. In case of thoracic spine, there is no significantly variable section. However, variation increases gradually with the passage of time so that it is assumed that noticeable value comes up in approximately 40 minutes. In case of lumbar spine, sharp increase of variation is seen in 20 minutes in translational and rotational direction. Conclusion : Without having corrections during the treatment, proper treatment time is considered as less than 15 minutes for cervical spine, 40 minutes for thoracic spine, and 20 minutes for lumbar spine. If treatment time is longer than these duration, additional patient alignments are required or PTV margin should be enlarged.

Background: Brain metastasis from cholangiocarcinoma (CCA) is a rare but fatal event. To the best of our knowledge, only few cases have been reported. Herein, we report the incident rate and a first case series of brain metastases from CCA. Methods: Between January 2006 and December 2010 5,164 patients were treated at Srinagarind hospital, Khon Kaen University; of those, 8 patients developed brain metastasis. Here we reviewed clinical data and survival times. Results: The incident rate of brain metastases from CCA was 0.15%. The median age of the patients was 60 years. Tumor subtypes were intrahepatic in 6 and hilar in 2 patients. All suffered from symptoms related to brain metastasis. Three patients were treated with whole-brain radiation therapy (WBRT), one of whom also underwent surgery. The median survival after the diagnosis of brain metastasis was 9.5 weeks (1-28 weeks). The longest survival observed in a patient in RPA class I with two brain lesions and received WBRT. Conclusion: This is a first case series of brain metastases from CCA with the incident rate of 0.15%. It is rare and associated with short survival time.

There are various types of malignancy in eyelid, such as squamous cell carcinoma, melanoma, and sarcoma. These malignant tumors have potential of metastasis by regional lymph node drainage. The lymph node around parotid gland has been known as a common site of regional lymph node metastasis. The rarity of malignant tumors in the periorbital area makes it difficult to determine the optimal extent of treatment. We report a case of parotid metastasis after eyelid cancer operation in a 60-year-old man.
