- Metastasized rectal cancer has long been considered incurable. During recent years, the treatment of rectal cancer patients has been improved, and nowadays, a subgroup of patients might even be cured. The aim of this study was to investigate the optimal timing of treatment in a multimodal therapy schedule in order to see whether the addition of bevacizumab (Avastin) to conventional chemotherapy was effective. The study included 39 patients with metastatic rectal cancer between 2009 and 2011, and three were excluded due to the lack of metastases or lack of follow-up information. The remaining 36 patients were divided into groups by treatment intention. The group with curative intention received mainly oxaliplatin (Eloxatin) in combination with capecitabine (Xeloda) with or without bevacizumab (Avastin) for 2 months followed by preoperative radiotherapy (RT) and surgery. Palliative patients had very different treatments depending on their needs of palliation. The median survival time for patients with curative intention was 31 months and for the palliative patients 12 months. Four of the patients (11%) with curative intention were considered cured at the end of follow-up. The response to chemotherapy after 2-month treatment is a good prognostic sign for which patients can be cured. Long-lasting palliation can be obtained with this treatment schedule. The main side effects were gastrointestinal events, including bowel perforation, neuropathy, thrombo-embolic disease and reduced general condition. All side effects are known, and the treatment is considered tolerable. We conclude that a good treatment schedule would be oxaliplatin (Eloxatin) in combination with capecitabine (Xeloda) with or without bevacizumab (Avastin) for 2 months, followed by preoperative RT and surgery.

- PurposeThe secreted protein acidic and rich in cysteine-like 1 (SPARCL1) is expressed in various normal tissues and many types of cancers. The function of SPARCL1 and its relationship to a patient's prognosis have been studied, whereas its relationship to radiation therapy (RT) is not known. Our aim was to investigate the expression of SPARCL1 in rectal cancer patients who participated in a clinical trial of preoperative RT.Methods and MaterialsThe study included 136 rectal cancer patients who were randomized to undergo preoperative RT and surgery (n=63) or surgery alone (n=73). The expression levels of SPARCL1 in normal mucosa (n=29), primary tumor (n=136), and lymph node metastasis (n=35) were determined by immunohistochemistry.ResultsTumors with RT had stronger SPARCL1 expression than tumors without RT (P=.003). In the RT group, strong SPARCL1 expression was related to better survival than weak expression in patients with stage III tumors, independent of sex, age, differentiation, and margin status (P=.022; RR = 18.128; 95% confidence interval, 1.512-217.413). No such relationship was found in the non-RT group (P=.224). Further analysis of interactions among SPARCL1 expression, RT, and survival showed statistical significance (P=.024). In patients with metastases who received RT, strong SPARCL1 expression was related to better survival compared to weak expression (P=.041) but not in the non-RT group (P=.569).ConclusionsSPARCL1 expression increases with RT and is related to better prognosis in rectal cancer patients with RT but not in patients without RT. This result may help us to select the patients best suited for preoperative RT.

- ObjectivesIncreasing evidence suggests that statins may have antitumor effects but their rolein rectal cancer appears inconclusive. The aim of this study was to investigate whether statins may have an impact on survival of older and younger patients with rectal cancer.Materials and MethodsThis study included 238 patients ≥70 years and 227 patients <70 years old, from the Southeast Health Care Region of Sweden, who were diagnosed with rectal adenocarcinoma between 2004 and 2013.ResultsIn the older group (n = 238), statin use at the time of diagnosis was related to better cancer-specific survival (CSS) and overall survival (OS), compared to non-use (CSS: Hazard Ratio (HR), 0.37; 95% CI, 0.19–0.72; P = .003; OS: HR, 0.62; 95% CI, 0.39–0.96; P = .032). In the older group with stages I-III disease (n = 199), statin use was associated with better disease-free survival (DFS) compared to non use (HR, 0.18; 95% CI, 0.06–0.59; P = .005). The improvement of CSS, OS and DFS remained significant after adjusting for potential confounders. In the older group with stage III disease, statin users had better CSS and DFS compared to non-users (log rank P = .043; log-rank P = .028, respectively). In the older group with short course radiotherapy, statin use was related to better CSS (log-rank P = .032). No such association was present in the younger group.ConclusionStatin use was related to improved survival in older patients with rectal cancer.This observation is important given the low cost and safety of statins as a drug.

- The prodrug capecitabine (Xeloda) has been an important drug for treatment for gastrointestinal cancer (GI-cancer). This study explores the efficacy of continuous metronomic Xeloda, as well as tolerability and best response during treatment. Patients (n=35) with stage IV GI-cancer were included in the study and were divided into two groups; upper (n=13) and lower (n=22) GI-cancer. All patients were given continuous metronomic Xeloda (500 mg×2). Best response was measured by radiological and clinical examination including laboratory results. Standard RECIST criteria were used. Median age was 66 (range 29-86). Those patients who received first and second line had the longest duration of treatment. For patients with metastatic gastrointestinal cancer, metronomic capecitabine (Xeloda) may be beneficial both as far as tumor control and quality of life is concerned. In this pilot study, palliation for more than 2 years is observed for 6 of the 35 patients.

- Background: Mucinous adenocarcinoma (MAC) represents 6-19 % of all colorectal carcinoma. It is associated with poorer response to chemotherapy and chemoradiotherapy. Case presentation: A 27-year-old Swedish woman presented with stomach pain and weight loss, and was diagnosed with locally advanced MAC in the transverse colon as well as 3 liver metastases. Neoadjuvant treatment with fluorouracil, folinic acid and oxaliplatin (FLOX) failed due to several infections, pulmonary embolism and deteriorated performance status. The patient was therefore considered palliative. Palliative treatment with metronomic capecitabine 500 mg x 2 daily and bevacizumab every other week were initiated. After 4 months of treatment the tumors had regressed and the patient was able to undergo radical surgery, thereby changing the treatment intention from palliative to curative. No adjuvant chemotherapy was given. There were no signs of recurrence 9 months later. Conclusions: The role of the combination of metronomic capecitabine and bevacizumab in patients with MAC merits further investigation.

- The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age greater than= 70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear. From two prospective Swedish databases, we assessed a cohort of 1021 patients who underwent curative surgery for stage I, II, or III primary CRC, with or without adjuvant chemotherapy/ radiotherapy. Of the patients with colon cancer (n = 467), 182 (39%) were aged less than70 years, 162 (35%) aged 70 to 80 years, and 123 (26%) were aged greater than= 80 years. Of rectal cancer patients (n = 554), 264 (48%) were aged less than70 years, 234 (42%) aged 70 to 80 years, and 56 (10%) aged greater than= 80 years. Older patients with either colon or rectal cancer had higher comorbidity than did younger patients. Older patients with colon cancer had equivalent postoperative morbidity and 30-day mortality to younger patients. Rectal cancer patients aged greater than= 80 years had a higher 30-day mortality than younger patients (odds ratio OR], 2.37; 95% confidence interval CI], 1.6-4.55; P = 0.03). For either colon or rectal cancer, adjuvant chemotherapy compromised the 5-year overall survival (OS) of older patients with stage II disease and had no effect on those with stage III disease. Receiving adjuvant chemotherapy was a poor factor of OS for older patients with either colon (HR 1.88, 95% CI: 1.20-4.35, P = 0.03) or rectal cancer (HR 1.72, 95% CI: 1.052.26, P = 0.004). Preoperative short-course radiotherapy improved both OS and local control for older patients with stage III rectal cancer and had no effect on those with stage II disease. Radiotherapy was a favorable factor for the OS of the older patients with rectal cancer (HR 0.42, 95% CI: 0.21-3.57, P = 0.01). In conclusion, Older CRC patients had equal safety of surgery as younger patients, except rectal cancer patients aged greater than= 80 years that had a higher mortality. Adjuvant 5FU-based chemotherapy did not benefit older CRC patient, while neoadjuvant radiotherapy improved the prognosis of older patients with stage III rectal cancer.
