Abstract
A 74-year-old man with anemia visited our department. Esophagogastroduodenoscopy showed a type 2 lesion from the angulus to the antrum. Histopathological findings indicated gastric neuroendocrine carcinoma. Colonoscopy showed a type 1 lesion at the cecum. Distal gastrectomy was performed with D1+lymph node dissection, Roux-en-Y reconstruction, and ileocecal resection with D3 lymph node dissection. The patient was pathologically diagnosed with large-cell neuroendocrine carcinoma in the stomach, pT4a(SE), med, INF a>>b-c, ly1-2, v1(SM, EVG), pN0, pM0, pStageⅡB, and adenocarcinoma (tub1>tub2)of the cecum, pT2(MP), ly1(HE), v1(EVG, SM), pN0, pM0, pStageⅠ. Postoperatively, he received oral S-1 as an adjuvant chemotherapy. His postoperative course was uneventful without any recurrence over 18 months.

Abstract
BACKGROUND AND AIMS Colorectal mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease. The purpose of this study was to investigate the clinical and endoscopic features of colorectal MALT lymphoma. METHODS Patients diagnosed with colorectal MALT lymphoma at Asan Medical Center from 2002 to 2016 were eligible. Medical records were reviewed to investigate clinical features and treatment outcomes. Endoscopic pictures were assessed to characterize the endoscopic features of colorectal MALT lymphoma. RESULTS A total of 51 patients were enrolled. The median age was 60 years (interquartile range, 55-71), and 21 (41%) were men. Twenty-six patients (51%) were asymptomatic. Forty-four patients (86%) were in early disease stages, namely Lugano stages I, II, and IIE. Endoscopic appearances were classified as 4 distinct types: subepithelial tumor type (26 patients, 51%), polyposis type (10 patients, 20%), epithelial mass type (7 patients, 14%), and ileitis type (8 patients, 16%). The rectum (20 patients, 39%) was the most common location, followed by the ileocecal area (15 patients, 30%). An initial endoscopic impression of lymphoma was made in only 7 patients. Forceps biopsy sampling as the initial tissue acquisition method could histologically diagnose MALT lymphoma in 28 of 35 patients (80%). Polypectomy as the initial histologic diagnosis could diagnose MALT lymphoma in 16 of 16 patients. Progression-free and overall survival rates at 5 years were 92% and 94%, respectively. CONCLUSIONS Colorectal MALT lymphomas show various endoscopic appearances, complicating the endoscopic suspicion of colorectal MALT lymphoma. The prognosis of colorectal MALT lymphoma was excellent.

Abstract
In June 1997, the patient underwent an operation for cecal colon cancer pStage II .I n May 1999, a liver metastasis at S6 was detected and the patient received a partial liver resection.In April 2004, a liver metastasis in S4 was detected and another partial liver resection was performed.In November 2008, he complained of hemoptysis and cough.The chest CT examination showed lymph node metastases in the mediastinum that invaded the left main bronchus.We performed chemo-radiotherapy for local control from January 2009. Because the lymph nodes were reduced remarkably and clinical complaints disappeared, we administrated a mFOLFOX6 regimen from June.We recognized the effect of treatment to be a complete response.In February 2014, we detected a lymph nodes recurrence around a right pulmonary artery.We performed chemo-radiotherapy again because the patient declined surgery.However, lymph node metastases did not completely respond.We then performed chemotherapy 30 times using a FOLFIRI plus panitumumab regimen.On PET-CT, the recurrent lesion did not show a hot spot.We experienced a case that responded to chemo-radiotherapy for long-term control of lymph node recurrence.

Abstract
There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.

Abstract
A 65-year-old woman underwent iliocecal resection for cecal cancer. During post-operative follow-up, she was diagnosed with metastasis to the abdominal wall and a curative resection was performed. After 12 courses of adjuvant chemotherapy with a modified combination of folinic acid, 5-fluorouracil, and oxaliplatin (mFOLFOX6), recurrence was noted in the lung. A curative resection was successfully performed and she was subsequently treated with bevacizumab and a combination of folinic acid, 5-fluorouracil, and irinotecan (FOLFIRI). One year after surgical resection, recurrence in the remnant lung was diagnosed. Because of the KRAS mutation, she could not be treated with anti-epidermal growth factor antibodies. The metastatic lung tumor continued to enlarge. Therefore, we selected regorafenib as third-line chemotherapy. After treatment with regorafenib, the size of the target lesion decreased significantly.

Abstract
Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract, histological and immunohistochemistry findings help to differentiate such tumours from other gastrointestinal malignancies. Metastasis is common to the stomach and small bowel and often presents with gastrointestinal bleeding. This is a case of an 82 year old man with an inguinal mass that following exploratory examination was found on histology to be a GIST metastases, imaging also showed pulmonary metastases. Following colonoscopy the primary caecal mass was found. Such metastatic presentations are extremely rare for this type of tumour. This case report highlights these unusual findings.

Abstract
A 33-year-old man, who underwent ileo-cecal resection and sigmoidectomy for concomitant cecal cancer and sigmoid colon cancer which was diagnosed during the emergent operation for the perforated acute appendicitis, suffered simultaneous multiple hepatic metastases. Postoperative hepatic aerial infusion chemotherapy with 5-FU was done (total dose 63 g), and the metastases were successfully disappeared (CR). Although 16-month passed from the operation, locoregional recurrence at the colorectal anastomosis and peritoneal dissemination were occurred. Aggressive resections of the recurrent sites (anterior resection of the rectum, ileum, ascending colon and other recurrent sites) and successive systemic administration of FOLFOX4(9-course), FOLFIRI (20-course) and capecitabine (15-course) were achieved. The patient survived for 4.5 years after the initial treatment.

Abstract
Mantle cell lymphoma (MCL) is a distinct subtype of non-Hodgkin lymphoma that remains incurable, and is associated with a median survival of approximately 5 years. Management of patients with relapsed or refractory disease is challenging. The major therapeutic goal in MCL management is to improve survival and quality of life whenever possible. Progress has been made in MCL therapy in the past decade based on clinical experimentation with novel agents and combinations. There is a growing list of conventional and novel agents in our armamentarium, consisting of not only additional chemotherapy combinations including high-dose approaches, but also biologically targeted reagents such as the monoclonal antibody rituximab, the proteasome inhibitor bortezomib, the mTOR inhibitor temsirolimus, immunomodulatory and antiangiogenic agents including thalidomide and lenalidomide, and cyclin-dependent kinase inhibitors, as well as a renewed interest in older compounds such as bendamustine and metronomic regimens. Efficacy evaluations for individual agents and rational combinations are in various stages of development, while treatment selection based on molecular and clinical prognostic scores is yet to be tested. In the absence of evidence demonstrating relative survival advantages of various second-line options, management of relapsed and refractory disease should be individualized. Involvement of a lymphoma center participating in clinical trials of novel MCL treatments is encouraged.

Abstract
Malignant triton tumor (MTT) is a rare, highly malignant nerve sheath tumor with rhabdomyoblastic differentiation. Initial debulking surgery followed by adjuvant therapy is the current treatment of choice, but has very limited efficacy when optimal cytoreduction is not achieved by surgical procedure. Neoadjuvant therapy for MTT, to potentially facilitate subsequent surgery, eradicate micrometastatic lesions and, therefore, improve the therapeutical outcome, has never before been presented in literature. Here, we report on the multimodal management of two cases of advanced and metastatic MTT. Treatment modalities involved neoadjuvant and adjuvant chemotherapy, surgical resection, and radiation. In both cases, integrated Positron Emission Tomography/Computed Tomography (PET/CT) emerged as an important diagnostic tool for the reliable assessment of MTT response and metabolic remission.

Abstract
Intestinal marginal zone B-cell lymphoma of the MALT type (I-MZL) is a relatively uncommon form of lymphoma. Twenty-seven patients with histologically-confirmed I-MZL were analyzed. The patients initially presented with abdominal pain (62.9%), and diarrhea (22.2%). The most common involved site was the ileo-caecal area (40.7%). Musshoff's stage I(E), II(E)1, II(E)2, III(E) and IV were present in 44%, 15%, 11%, 7.4% and 22% respectively. Sixty-three percent were in the low-risk group according to the Follicular Lymphoma International Prognostic Index. Complete response and partial response were achieved in 82% and 4% patients. The estimated 5-year overall survival (OS) and progression-free survival (PFS) rates were 86% and 54%. Stage > or = II(E)2 was determined to be a poor prognostic factor for PFS and OS. I-MZL commonly manifests in an early-stage, low-risk state and tends to respond well to local and systemic treatment with favorable prognosis. I-MZL tends to be an indolent disease - characterized by prolonged survival with frequent relapses, similarly to other site MZLs.

Abstract
BACKGROUND Prostatic carcinoma is the second most common cause of cancer-related deaths in males in the West. Approximately 20% of patients present with metastatic disease. We describe the case of a patient with metastatic prostate cancer to the bowel presenting clinically and radiologically as a primary caecal cancer. CASE PRESENTATION A 72 year-old man presented with abdominal discomfort and a clinically palpable caecal mass and a firm nodule on his thigh, the latter behaving clinically and radiologically as a lipoma. Computed tomographic (CT) scan showed a luminally protuberant caecal mass with regional nodal involvement. The patient was being treated (Zoladex) for prostatic cancer diagnosed 6 years previously and was known to have bony metastases. On admission his PSA was 245.4 nmol/ml. The patient underwent a right hemicolectomy. Histology showed a poorly differentiated adenocarcinoma which was PSA positive, confirming metastatic prostatic adenocarcinoma to the caecum. The patient underwent adjuvant chemotherapy and is free from recurrence a year later. CONCLUSION Metastasis of prostatic carcinoma to the bowel is a very rare occurrence and presents a challenging diagnosis. The diagnosis is supported by immunohistochemistry for PSA. The treatment for metastatic prostate cancer is mainly palliative.

Abstract
Ketamine is a hypnotic pharmacon with high analgesic potency. Ketamine is an agent blocking NMDA-receptors and involves opioid receptors, the voltage-gated sodium-channel, cholinergic receptors and the monoaminergic descending inhibitory pathways. Besides its influence in chronification of pain, NMDA-R is crucial in induction and maintainance of visceral pain, attentional perceptual processes and emotional valuation of pain. The analgesic potency of S-+-Ketamine doubles racemic Ketamine's analgesic potency. Thus the incidence of CNS-side effects ought to be reduced to 50% in equianalgesic dosages. Evidence supports the assumption that continuous infusion of S-+-Ketamine 2.5-5 mg/hour is effective in treating visceral pain of high intensity. In the presence of chronic pain states the effect ought to be more marked. There is evidence that the probability of psychotomimetic side effects does not exceed 10%. The rate of side effects can further be minimized through careful titration and prophylaxis (or treatment) with Diazepam 1 mg i.v.

Abstract
Cecal extrapulmonary small cell carcinoma (cESC) is extremely rare, with only single previous report of occurrence in a child. We report a 76-year-old man admitted for evaluation of a cecal mass seen in colonoscopy. Histology revealed small cell carcinoma with classic immunohistochemical profile similar to those seen in the colon. Further clinical survey documented absence of any other masses or abnormality. To the best of our knowledge, this is the first case of primary cESC occurring in an adult. Awareness of the pathologist and clinician of the cecum as a potential site of cESC may help to prevent misdiagnosis as poorly differentiated adenocarcinoma. This is crucial because extrapulmonary small cell carcinomas usually have worse prognosis.

Abstract
BACKGROUND Colorectal cancer is one of the most common forms of gastrointestinal cancer in the world today. In the Asia-Pacific area, it is the fastest emerging gastrointestinal cancer. AIM To determine the basic demographic features of patients with colorectal cancer and the anatomic distribution and characteristics of the tumour in a local Asian population. METHODS We conducted a review of consecutive patients who had undergone colonoscopy from 1999 to 2003 at the University of Malaya Medical Center, Kuala Lumpur, Malaysia. RESULTS Analysis was carried out on 3404 patients who underwent colonoscopy. A total of 228 patients (7%) were diagnosed with carcinoma. The mean age of diagnosis (+/-s.d.) was 64.4 +/- 13.1 years. The male to female ratio was 1.15. Polyps were noted in 470 patients (14%). Polyps detected concomitantly with a colorectal cancer were noted in 55 patients (2%). Four patients (0.1%) were diagnosed to have familial adenomatous polyposis coli. Of the 228 patients 209 (92%) had tumours at only one site whereas 19 (8%) had synchronous lesions. Tumours were mainly left sided [198 of 248 patients (80%)] with the majority located in the recto-sigmoid region. Detailed records of treatment were available only in 176 patients. A total of 147 of 176 patients (84%) underwent surgery and 50 (28%) also received adjuvant or palliative chemotherapy (28%). Seven of 154 patients (5%) were diagnosed to have stage A cancers, 64 (42%), stage B, 23 (15%), stage C and 60 (39%), stage D. Multivariate analysis using multiple logistic regression analysis showed that age > or =65 years (OR = 1.78; 95% CI: 1.35- 2.36) and Malay (OR = 2.09; 95% CI: 1.30-3.35) and Chinese (OR = 1.77; 95% CI: 1.77-2.69) race were significant independent predictive factors for colorectal cancer. CONCLUSIONS The demography of colorectal cancer is different from western patients. Tumours were mainly left sided in our patients. However, no differences in anatomic location were found between races, men and women and younger and older age groups. Colorectal cancer presented in an advanced stage in the majority of patients.

Abstract
A 66-year-old man underwent a curative operation for cecal cancer on the 30th of November, 1998. Since his CEA level rose in January 2001, computed tomography (CT) revealed a tumor in the abdomen. He underwent a resection of this tumor and disseminated tumors that were diagnosed during the operation. He received systemic chemotherapy (5'-DFUR 600 mg 3x everyday, CPT-11 80 mg/body div every 2 weeks), but the CEA level rose again in August 2003. He was diagnosed with spleen metastasis and underwent splenectomy. The tumor disseminated in the left diaphragm was also resected. After that, he received systemic chemotherapy (5-FU 500 mg/body/week div, levofolinate calcium 250 mg/body/week i.v.) as an outpatient. Peritoneal carcinomatosis from colorectal cancer with distant metastasis, in general, has no indication for an operation. However, if dissemination is located after a sufficient observation period, its resection may be recommended.

Abstract
Approximately 40% of patients treated with curative intent for colorectal carcinoma eventually recur. In about one third of these patients, the lesion is localized and potentially resectable. Typically, the recurrence is characterized by findings on diagnostic imaging studies and may be accompanied by a rise in the serum carcinoembryonic antigen (CEA) levels. In a few patients, however, the asymptomatic rise in CEA is not accompanied by diagnostic findings on computed tomography (CT). We report a case herein, of a patient with rising CEA, noted 1 year after completion of adjuvant chemotherapy for node-positive colorectal cancer. CT and laparoscopic exploration were nondiagnostic. In order to further evaluate the rise in CEA, positron emission tomography (PET) was performed. PET revealed an area of increased uptake in the right lobe of the liver. Resection of the metastatic liver lesion resulted in a subsequent drop in the CEA levels.

Abstract
Thirty-five patients received 105AD7 human anti-idiotype vaccination prior to surgery for colorectal carcinoma. Patients were immunized before and also received one to two immunizations after surgical resection of their colorectal cancer. The vaccine was well tolerated with no associated toxicity. Lymphocytic infiltration within the resected tumors was quantified by immunohistochemistry and image analysis. Enhanced infiltration of helper T cells (CD4) and natural killer (NK) cells (CD56) were observed in the tumors from immunized patients when compared with tumors from stage, grade, site, age, and sex matched unimmunized patients. NK activity was increased in the blood, peaking 7-10 days post immunization and then dropping rapidly and correlating with NK extravasation within the tumor. Comparison of the amino acid sequences of 105AD7 anti-idiotype and the antigen it mimics, CD55, has predicted that patients with HLA-DR1, HLA-DR3, and HLA-DR7 haplotypes should show helper T cell responses following 105AD7 vaccination. Eighty-three percent of patients expressing these haplotypes responded to 105AD7, whereas 88% of patients who failed to express these haplotypes were nonresponders. With a median follow-up of 4 years (range, 2.5-6 years) 65% of patients remained disease free. This trial shows that 105AD7 stimulates antitumor inflammatory responses allowing extravasation within tumor deposits of both helper T cells and NK cells. This represents a way of evaluating immune responses in patients both within the blood and at the tumor site. The study confirms that immunization with a human anti-idiotypic antibody results in immune responses in 83% of patients with a permissive haplotype.

Abstract
The aim of this study was to identify the principal deficiencies and difficulties associated with the treatment of primary digestive lymphomas at Yaounde. We analyzed the medical records of 46 patients treated at Yaounde General Hospital over a period of 7 years (January 1989 to December 1996). The study population consisted of 24 men (52%) and 22 women (48%), giving a sex ratio of 1.08. The mean age of the patients was 49 years (range: 18 to 80 years). The treatment of these patients was not always optimal, due largely to socioeconomic and technical factors. We observed cases of very late diagnosis in which the histological data were imprecise or incomplete, in the absence of modern histological techniques. Assessment of the expansion of tumors was frequently inadequate, due to the absence of scanners or the inability to pay for their use. These problems, and the high cost of chemotherapy and radiotherapy, have severely limited the efficacy of treatment, resulting in poorer responses to treatment than reported elsewhere. In conclusion, national solidarity and cooperation at the regional and international levels seem to be necessary in these clinical conditions, to overcome these obstacles and to improve the quality of treatment for patients in general, and for those with primary digestive lymphomas in particular.

Abstract
We report a case of cancer of the caecum in a 71-year-old male who presented with parietal mesh abscess. Two years before, he was treated for a right inguinal hernia by insertion of a Dacron mesh. CT scan then colonoscopy determined the existence of a voluminous caecal tumor perforated in the abdominal wall with an important abscess around the mesh. Right colectomy and parietal muscles excision were performed completed with postoperative radiochemotherapy. At 2 years, there is no evidence of recurrence. Atypical features with a hernia mesh repair associated with a sudden change in the patient's condition should alert the clinician to the possibility of a further subjacent pathological process.

Abstract
We report a retrospective series of 28 patients with Krukenberg tumors treated at the Gustave Roussy Institute from 1973 to 1990. Mean age of these women was 42 years. The patients were classed into two groups: depending on whether the ovarian metastasis (group 1) or the primary cancer (group 2) was discovered first. The primary tumor was identified in 20 cases (18 cases of linitis, 1 tumor of the cecum, 1 tumor of the appendix). The primary tumor remained unknown in 8 cases. Twenty-seven patients underwent radical total hysterectomy or bilateral adnexectomy. Gastrectomy was possible for 11 of the 18 cases of linitis; hemicolectomy and appendectomy were performed for the cecal and appendicular tumors respectively. Diagnosis of a primary tumor of the appendix was made after systematic appendectomy and of two Krukenberg tumors after systematic bilateral adnexectomy. In the first group of patients, both localizations were treated in 6 cases, one in 12 including 4 because gastrectomy was not initially possible and in 8 because the primary tumor was unknown. In the second group, the two localizations were treated in 7 cases, and one in 2 cases because gastrectomy was not possible. Surgery was not performed in one patient due to diffuse carcinosis. Bilateral ovarian metastases were seen in 26 out of the 28 cases and 26/28 had chemotherapy without any appreciable effect. Bone metastasis predominated (9 cases), followed by pleuropulmonary (5 cases) and liver (3 cases) metastasis. Overall median survival was 20 months; 14 months in the first group and 29 months in the second. Appendectomy and exploration of the colon and the stomach were performed in all cases in which the Krukenberg tumor was discovered intraoperatively. An endosonographic exploration of the stomach is recommended if the primary tumor is not localized. Bilateral adnexectomy should always be performed in patients with linitis whatever the age. Surgical treatment of the two localizations is not always sufficient for cure.

Abstract
OBJECTIVE To review the breed, age, gender, clinical and laboratory findings, treatment and outcome of horses with caecal disease presented to a referral centre. DESIGN Retrospective study of 96 cases. PROCEDURE The breed, age, and gender of the study population were compared with the corresponding hospital population for the same period. The means (+/- SD) for clinical and laboratory findings were recorded for each caecal disorder. Treatment was categorised as medical or surgical, and outcome was recorded. RESULTS Caecal diseases included impaction (40% of total cases), rupture associated with concurrent unrelated disease (13%), rupture with parturition (9%), rupture with no associated disease (5%), infarction (11%), torsion (9%), abscess or adhesion (7%), tumour (3%), and miscellaneous conditions (3%). The breed or gender of affected horses did not differ from the hospital population, although horses > 15 years were more frequently represented (P < 0.05). This age group was specifically more predisposed to caecal impaction (P < 0.05), as were Arabian, Morgan, and Appaloosa breeds (P < 0.05). In horses with caecal impaction transrectal examination was the most useful diagnostic procedure; 90% of affected horses treated medically were discharged while horses treated by typhlotomy alone, or typhlotomy and blind end ileocolostomy, had survival rates to discharge of 71% and 86%, respectively. Horses with caecal rupture associated with concurrent un-related disease showed no signs of impending rupture; all were receiving phenylbutazone, all were euthanased, and 50% had caecal ulceration at necropsy. Of horses with caecal rupture with parturition 56% had prior dystocia; in two-thirds the site of rupture was the ileocaecal junction and all were euthanased. Horses with caecal rupture with no associated disease died or were euthanased; rupture was idiopathic. Horses with caecal infarction usually had signs of abdominal pain and abdominal fluid changes consistent with peritonitis; transrectal examination was nonspecific, and typhlectomy was successful in seven of eight horses. Horses with caecal torsion had signs of severe, acute abdominal pain and typhlectomy was successful in three of five horses. Diagnosis of caecal adhesion or abscess was assisted by transrectal palpation in two of seven horses and surgical treatment was successful in two of five horses. A caecal tumour was diagnosed in three horses aged 20 years or older that presented with chronic weight loss. Other caecal diseases were uncommon. CONCLUSION Caecal disease is uncommon in equids but some specific features of the history and physical findings can alert the veterinarian to the possibility of caecal involvement in horses with gastrointestinal dysfunction. Medical or surgical therapy can be effective in horses where caecal rupture has not occurred.

Abstract
An unusual case of aggressive Stage IIE(B) primary natural killer cell lymphoma of the caecum is described in a 16-year old Chinese girl. The immunophenotype of the tumour cells was CD2+, CD3-, CD4-, CD5-, CD7+, CD8-, CD45RO+, CD45RA-, CD56+, CD57-. Southern blot analysis showed a normal germline arrangements of the T-cell antigen receptor and immuno-globulin heavy chain genes. This lymphoma pursued a highly aggressive clinical course, with the rapid development of an extensive local recurrence after an apparently complete resection and combination cytotoxic therapy. The patient died 7 months after diagnosis, despite receiving salvage treatment. Given the aggressiveness and poor prognosis in this biologically distinct primary gastrointestinal lymphoma, a more vigorous systemic therapy should be considered in addition to surgery.

Abstract
Synchronous lymphoma and adenocarcinoma of the colon are extremely rare. A 32-year-old woman was referred to us for colon cancer. Investigations revealed two primary tumors, one in the cecum and the other in the sigmoid colon. Subtotal colectomy with ileorectal anastomosis was performed. Histology revealed the cecal tumor to be non-Hodgkin's lymphoma, diffuse small cell type with plasmacytoid features. The sigmoid colon tumor was moderately differentiated adenocarcinoma. The patient received 6 cycles of chemotherapy postoperatively for lymphoma but died of recurrent disease after 17 months.

Abstract
A rare adult case of intussusception caused by malignant lymphoma of the cecum with intramural metastasis is reported. The patient was a 24-year-old man. Ileocolic intussusception was diagnosed by characteristic findings on abdominal computed tomography. Endoscopic examination revealed a massive protuberant tumor, 3 cm in diameter, and a semipedunculated polyp, 1 cm in diameter, in the cecum, which had caused the ileocolic intussusception. Endoscopic biopsy specimens failed to yield a definitive diagnosis histologically, but right hemicolectomy with lymph node dissection was performed. On histologic examination of the surgical specimens, both the tumor and the polyp were diagnosed as diffuse lymphoma of medium-sized cell type, and no lymph node involvement was found. The patient responded well to surgical and chemotherapeutic treatment, and has had no recurrence of malignant lymphoma in the 2 years since the surgical treatment. This was a very rare case of an intussusception in an adult patient due to malignant lymphoma in the cecum with intramural metastasis and without lymph node involvement.

Abstract
Boanmycin (bleomycin A6, BM), an antitumor antibiotic, was conjugated to monoclonal antibodies including R19, H111 and CCT2. The immunoconjugates exhibited selective cytotoxicity to related target cells including cecum cancer Hce-8693 cells, liver cancer BEL-7402 cells and leukemia CEM cells. They were highly effective against related human tumor xenografts in nude mice, and the inhibition rates by the conjugates were much higher than those by free BM. The inhibition rate by R19-BM conjugate against human cecum cancer xenografts reached 90%. BY immunoelectron microscopy, CCT2-BM conjugate showed specific binding and internalization in leukemia CEM cells. The results indicate that boanmycin-monoclonal antibody immunoconjugates are highly active both in vitro and in vivo.

Abstract
A metastatic model of human colon cancer has been previously established using orthotopic onplantation of histologically intact in tissue nude mice. In this study, effects of immunochemotherapy using OK-432, 5-fluorouracil (5-FU) and mitomycin C (MMC) on Col-2-JCK, a human colon cancer xenograft, were evaluated using this model. When 5-FU and MMC were administered without OK-432, liver metastases were not reduced even at maximum tolerated doses of both drugs, although cecal tumor growth was significantly reduced. On the other hand, when combined with OK-432, both 5-FU and MMC reduced liver metastases with synergistic reduction of cecal tumor growth, demonstrating the potential of combining immunotherapy with chemotherapy against metastases.

Ischemic injury to the gallbladder has been described after hepatic artery embolization but has not been considered a clinically significant complication of this procedure. We present three cases in which therapeutic embolization resulted in symptomatic gangrenous cholecystitis requiring urgent surgical intervention. Clinical parameters that distinguish this infrequent ischemic septic process from the more common postembolization syndrome are discussed and recommendations concerning the diagnosis and management of these complicated patients are outlined.

Abstract
The paper reports a case of submucous lipoma of the cecum. The difficulty of clinical diagnosis is underlined on account of aspecific symptoms, and in fact it is uncommon for diagnosis to be made on the basis of X-rays. Colonoscopy, in particular using bioptic techniques, allows the nature of the lipoma to be diagnosed, and in addition may act as an excellent therapeutic instrument.

Abstract
Twenty-two patients with primary ileocecal non-Hodgkin's lymphoma were reviewed. Abdominal pain (67%), altered bowel habits (50%), and weight loss (50%) were the most common presenting symptoms and an abdominal mass was palpable in 50%. Sixteen (73%) had histologic evidence of local lymph node involvement at diagnosis and another two (9%) had nonhistologic evidence of nodal involvement. An abdominal computed tomography (CT) scan was the most helpful staging investigation. Twenty-one (95.5%) patients underwent surgical resection of their disease. Subsequent chemotherapy, with or without radio-therapy, appeared to prolong survival (median, 34 months versus 14 months). There were three treatment-related deaths. Neither the age of the patient nor the stage of disease at presentation (Ann Arbor) appeared to influence survival. Adequate initial surgery combined with chemotherapy may provide optimum therapy in patients with primary ileocecal lymphoma.

Abstract
Between January 1977 and January 1988, 19 patients with non-Hodgkin's lymphoma (NHL) involving the ileocaecal region were cared for by the CRC Wessex Medical Oncology Unit. Fifteen of these patients had primary ileocaecal NHL (stages IE or IIE) and four had secondary involvement of this region (stage IV). The commonest clinical presentation was with abdominal pain and a palpable mass in the right iliac fossa. Bulky (greater than 10 cm) disease was a particularly common feature, and complete surgical removal was possible in only seven patients. All patients had intermediate (18) or high grade (one) NHL using the Working Formulation. The commonest histological subtype was diffuse large cell. Seventeen patients received postoperative therapy, comprising local radiotherapy in one and combination chemotherapy in the remaining 16. Eleven of the 19 patients remain disease-free 6-60 months from diagnosis. Because of the high incidence of bulky disease at this site, postoperative therapy may be indicated, even for patients with apparently completely excised stage I disease.

Abstract
The efficacy of radiation therapy combined with local hyperthermia is demonstrated by three case studies. Mode of action and problems are discussed and published results reported. Human tumour cells obtained of biopsies from our patients before the onset of treatments were investigated. The short time cell cultures were treated either with hyperthermia or irradiation alone or with combinations under the same conditions as the clinical treatments. We could clearly demonstrate that cell cultures of human origin respond to irradiation or hyperthermia. But the effect was limited and only cultures treated with combined modalities did not relapse. There is hope that mega-voltage radiation complemented with hyperthermia have a similar effect as high-LET-radiation. Side effects have been moderate so far using an extended clinical use.

Abstract
Forty patients with invasive regional-stage adenocarcinoma of the large bowel and rectum received adjuvant postoperative chemotherapy combined with doses of radiation below the maximal tissue tolerance level. This treatment was reserved for patients with stage B2, C1, and C2 lesions, with only two exceptions. The treatment was well tolerated. It appeared to result in a longer disease-free interval when compared with population-based results for patients with sigmoid cancer who had surgery alone. Our results paralleled those of the Gastrointestinal Tumor Study Group (GITSG) for combined adjuvant therapy of rectal cancer, who also indicated an advantage for long-term survival. Patients who received additional extended chemotherapy had at least the same percentage of favorable outcomes. Tumors above the peritoneal reflection also appeared to share the same improved results. We believe a multicenter randomized study should be performed to evaluate this group of patients.

Abstract
Preoperative radiation therapy is one of the major indications for the use of ionizing radiation in the treatment of malignant disease. The preoperative application of radiation treatment is given with the intention of reducing the size of bulky cancers, thus converting unresectable tumors into resectable ones. Other benefits are reduction in the risk of locoregional recurrence and in the risk of blood-borne dissemination of malignant cells promoted during surgical resection.This paper presents and discusses three cases of unresectable intrapelvic tumors initially treated by radiation therapy with the primary goal of palliation. These three cases included rectal, cecal, and uterine carcinoma. In each case, a preoperative radiation dose of 4500 to 5000 cGy was delivered. Evaluations during and after the completion of the radiation treatments revealed that the tumor responded remarkably well to the treatment, which encouraged the surgical intervention; at surgery, minimal tumor was found. These three patients are alive to date without apparent evidence of disease.

Abstract
Seven patients with progressive ileal or caecal carcinoid tumors and liver metastases were treated with human recombinant alpha-interferon (IFN alfa-2b) at a dosage of 2-4 x 10(6) U daily or every other day subcutaneously. Six patients had symptoms of the carcinoid syndrome. No change of tumor size lasting 4 to 40+ months (median, 18 months) was noted in 6 patients, and 1 patient had hepatic tumor progression. A decrease in urinary excretion of 5-hydroxyindoleacetic acid by more than 50% lasting 2-11 months (median, 4) was observed in 5 patients. Four patients were completely or partially relieved of flushing, diarrhea, obstruction or abdominal pain. The side-effects were negligible with the exception of mild fever, headache and confusion only during the first days of therapy. Treatment with IFN alfa-2b offers good palliation to patients with disseminated ileal or caecal carcinoid tumor and carcinoid syndrome.

Abstract
The natural history of surgically treated adenocarcinoma of the cecum has not been well defined. This report is a retrospective study of 106 patients followed for a median time of 25 months after hemicolectomy. The overall median survival rate was 73 months and the median disease-free survival rate was 37 months; 22 of 106 patients failed locally (21%). In addition, 7 of these 22 patients had distal failure. Thus, there appears to exist a group of patients likely to benefit from adjuvant radiotherapy. Whether total abdominal irradiation or locoregional radiotherapy is the method of choice needs to be further defined.
