Occupational therapy for elderly. Evidence mapping of randomised controlled trials from 2004-2012.

OBJECTIVE: Previous systematic reviews on occupational therapy for elderly included studies until 2003. The present evidence mapping summarizes recent evidence for the efficacy of occupational therapy with older persons based on randomised controlled trials from 2004-2012. METHOD: An electronic search in Cochrane and Medline databases identified publications of randomised controlled trials on occupational therapy interventions for persons≥65 years old. Two raters independently extracted data and analysed the quality of samples, interventions and outcome evalutations according to PRISMA criteria. RESULTS: In all, 136 abstracts were identified and 48 studies analysed, from these 12 on stroke, 15 on falls and mobility, 7 on dementia, 4 on prevention and 10 on other conditions. Reports of adverse events and evaluations of costs and long-term outcomes are frequently lacking. CONCLUSION: The most promising fields for further research are primary and secondary prevention in persons with stroke, falls or mobility problems and tertiary prevention in persons with dementia. Future trials should be conducted and reported according to consented reporting guidelines of the equator network.

[CT-guided electrode placement for sacral nerve stimulation in the treatment of faecal incontinence (cSNS)]. / CT-gesteuerte Elektrodenplatzierung zur Sakralnervenstimulation bei Stuhlinkontinenz (cSNS).

BACKGROUND: The sacral nerve stimulation (SNS) can be performed in the screening phase under local anaesthesia. Implantation of the tined-lead electrodes is usually performed in an inpatient setting under general anaesthesia. An outpatient procedure for both PNE and implantation of the electrodes offers decisive advantages with respect to the accuracy of electrode placement. MATERIALS AND METHODS: From 2006 to 2011 a total of 51 patients was treated with SNS in an outpatient setting. RESULTS: Of 51 patients having the PNE, in four patients the procedure could not successfully be completed. In 39 of the 47 patients screened, the testing was positive. Eight times the screening was negative. The functional results show a significant decline in the Cleveland scores from 14.9 to 6.4. The manometric resting pressure improved from 23.4 mmHg to 43.81 mmHg, the squeezing pressure improved from 42.2 mmHg to 76.12 mmHg. Due to patients' perception and according to the response on the stimulus, the electrodes were placed on the left in S4 11 times, 23 times in the left S3, 3 times in the right S3, once in the left S2 and once in the right S2. CONCLUSION: CT-guided electrode placement is safe for temporary (subchronic) and permanent (chronic) sacral nerve stimulation and provides a valuable means for placement of the stimulating material.

[Sacral nerve stimulation (SNS) in the treatment of faecal incontinence]. / Die sakrale Nervenstimulation im Behandlungskonzept der Stuhlinkontinenz.

Sacral nerve stimulation (SNS, sacral neuromodulation) has become an important tool in the treatment of incontinence. Idiopathic, muscular as well as neurogenous disorders can be treated successfully with this method. Possible complications like infections, cable breaks and electrode displacements may be treated very well conservatively. However, in some patients a surgical revision or removal of the stimulation system may be necessary.

Cooperate concept of metastasis: site-specific requirement of activated differentiation and dynamic deterioration.

Cancer metastasis results from positive and negative cellular events such as constitutive activation of oncogenes (cOA) or genetic losses (GL) being modulated by downstream signals of epithelial-mesenchymal or mesenchymal-epithelial transition, thus constituting master programs of metastatic phenotype and site specificity. To address the complex nature of these programs, we introduced clinical and phenotypic markers like tumor size, grade, cellular shape, or expression of E-cadherin in 27 colon cancer (CC) patients (cOA and GL), and 41 patients with gastrointestinal stromal tumors (GIST, cOA) to produce scores of cOA and GL. Scores of cOA were highest in case of hepatic and lower in case of an isolated peritoneal spread (GIST), or (CC) of both, cOA and GL, highest in case of a combined hepatic and peritoneal spread and lower in case of an isolated peritoneal spread; but in case of an isolated hepatic spread, scores of cOA were high and low of GL. This indicates a differential contribution of cellular dissociation and recognition in site-specific metastasis, of cOA predominantly in production of hepatic and in the case of GL of serosal spread.

New selective endoscopic sacral nerve root stimulation--an advance in the treatment of fecal incontinence.

BACKGROUND: Fecal incontinence (FI) is a major part of illness and physical discomfort in the general population. Since the 1990s, sacral nerve stimulation has been well established in the treatment of neurogenic FI. The precise placement of the electrode is crucial for the success of the procedure. Eighty percent of the patients benefit from permanent treatment, but in 10-20% of the patients tested electrode placement proves impossible due to anatomical variations of the sacral foramina. In this study, we describe the technical requirements and a new method of electrode placement with reference to the anatomical (bone) landmarks in an animal model. METHODS: With a small endoscope (Verres needle), we accessed the perirectal space to identify the nervous structures. A stimulated sphincter EMG was obtained for the experimental animals and muscle action potential (MAP/M-wave), latency time [ms], and the amplitude of the motor response [µV] were recorded. Electrodes were placed, the animals killed and dissected leaving the pelvic cavity untouched. The specimens were examined in a magnetic resonance scanner and in a multi-slice computed tomography scanner to detect the electrode material and possible surgical complications. After that the specimens were dissected. KEY RESULTS: In all eight cases in the four animals tested, we were able to stimulate the sacral nerve as demonstrated by the EMG findings. No major surgical complications were observed for the procedure. CONCLUSIONS & INFERENCES: Endoscopic sacral nerve root stimulation is a safe and effective method for delivering stimulation material in the pelvis of the sheep. It is a promising procedure to be tested in humans.

[Treating vaginismus in Turkish women]. / Vaginismusbehandlung bei türkischen Frauen.

OBJECTIVES: Vaginismus is a sexual dysfunction involving various branches of medicine, including psychiatry and gynaecology. Psychiatric help is sought in only a small proportion of cases, although it is probable that the psychopathological aetiology is more frequent than generally recognized. This article deals with the causes and psychological circumstances in four Turkish couples who presented with unconsummated marriage for 3 to 7 years. Vaginismus F52.5 to the ICD-10 is a sexual dysfunction characterised as: deep anxiety about coitus leading to extreme spasm of musculature making coitus impossible or extremely unpleasant and painful. PATIENTS AND METHODS: Four Turkish couples with unconsummated marriage due to the female partners' penetration phobia were included to this study. A patient-oriented multidimensional individual treatment (combination therapy) is a cost effective, short-term (typically 10- to 12-week) treatment model for both partners. It includes some elements of cognitive behavioural therapy and systemic partner therapy which were considered not radically different from previous therapeutic strategies. RESULTS: Results were successful in all cases; the couples were extremely satisfied with having a normal sex life for the first time. This led to desired pregnancies and avoiding of possible breakdown of their families. DISCUSSION: The couples did well with combination behavioural therapy. This methodology is discussed in its various aspects and with a cultural background. We also emphasise the need for physicians to be mindful of cases of vaginismus requiring psychiatric intervention rather than gynaecological treatment.

[Score prediction of metastatic risk in Gastrointestinal Stromal Tumours (GIST)]. / Entwicklung eines Malignitätsscores zur Vorhersage der Metastasierungswahrscheinlichkeit Gastrointestinaler Stromatumoren (GIST).

The purpose was to generate a score targeted at the metastatic risk potentially reflecting oncogenic activation in Gastrointestinal Stromal Tumours (GIST). In 41 patients size and location of the primary, mitotic index, initial symptoms, and histological appearance were rated with 0 to 1 or 2 points. The course of the disease was recorded as incidental, symptomatic, locally recurrent, with peritoneal dissemination, or with hepatic spread. The parameters tumour size (p < 0.001), mitotic index (p < 0.001), localisation of the primary (p < 0.001) and symptoms (p < 0.05) correlated with the course of the disease. This correlation was highly significant (p << 0.0005) when the overall score was applied, the median being 0 in incidental, 3 in symptomatic, 4 in locally recurrent, 4.5 in peritoneal, and 5 points in hepatic spreading GIST. Results were compared with those of an established risk stratification. The sensitivity and specificity of a score > 4 for the occurrence of liver metastases were 100 and 73.5 % compared with 85.7 and 82.4 % for a high risk profile according to Franquemont's classification. The results indicate the ability of routinely recorded data to predict the metastatic outcome of GIST.

[Quality indicators for diagnostic and therapy of rectal carcinoma]. / Qualitätsindikatoren bei Diagnostik und Therapie des Rektumkarzinoms.

Diagnostic and treatment of rectal cancer need a continuous quality assessment. Indicators of quality were compiled as indicator profile for a summarizing evaluation. The indicators selected should potentially show an appreciable variation of the quality target and in addition should be decisive for the outcome. For the evaluation of the clinical diagnostic the frequency of the determination of the pretherapeutic T, N and M categories and the proportion of pT 1-tumors were chosen, for the pathological diagnostic the number of histologically examined lymph nodes and the proportion of lymphnode positive patients. Process quality of treatment was defined by the following indicators: proportion of tumor excision, of definite therapy by local tumor removal, of neo-adjuvant long-term radiochemotherapy, of adjuvant treatment in patients not selected for neoadjuvant therapy, of total / partial mesorectal excision, of abdomino-perineal resection, postoperative mortality, frequency of clinically apparent anastomotic leakage, and of neurogenic bladder dysfunction at hospital discharge. The indicators for the quality of the performance of treatment were differentiated between surrogate indicators that can be determined immediately after accomplishment of primary surgical therapy giving strong clues for the further course of disease at an early date, and definite indicators. Important surrogate indicators comprise the occurrence of intraoperative local tumor cell dissemination, R 1 / 2-resection, pathohistologically CRM-positive tumor resection, and the quality of mesorectal excision (proportion of incomplete mesorectal excision). The definite indicators include the 5-year local recurrence rate and the 5-year overall survival rate. The corresponding quantifying parameters for the individual indicators are specified in this paper with precise figures.

[Report on the workshop "workflow rectal cancer II" in Burghausen]. / Bericht über den Workshop "Workflow Rektumkarzinom II" am 10. / 11.11.2006 in Burghausen.

The task force "workflow rectal cancer II" defined operative techniques in lower rectal cancer, especially the total mesorectal excision and an improved technique of abdominalperineal resection. New aspects for treatment of rectal cancer with primary distant metastases are described. Due to newer publications a concept of bidirectional procedure with surgery and radiochemotherapy is recommended, where the operation must not be inevitably the first step. In anastomoses below 6 cm of the anocutaneous verge a reservoir should be performed on principle due to better functional results. The colon-j-pouch with a maximal loop length of 6 cm is best investigated under these conditions, the other procedures should be further evaluated.

Unmet needs in the diagnosis and treatment of dyslipidemia in the primary care setting in Germany.

OBJECTIVES AND METHODS: DETECT is a cross-sectional study of 55,518 unselected consecutive patients in 3188 representative primary care offices in Germany. In a random subset of 7519 patients, an extensive standardized laboratory program was undertaken. The study investigated the prevalence of cardiovascular disease, known risk factors (such as diabetes, hypertension and dyslipidemia and their co-morbid manifestation), as well as treatment patterns. The present analysis of the DETECT laboratory dataset focused on the prevalence and treatment of dyslipidemia in primary medical care in Germany. Coronary artery disease (CAD), risk categories and LDL-C target achievement rates were determined in the subset of 6815 patients according to the National Cholesterol Education Program (NCEP) ATP III Guidelines. RESULTS: Of all patients, 54.3% had dyslipidemia. Only 54.4% of the NCEP-classified dyslipidemic patients were diagnosed as 'dyslipidemic' by their physicians. Only 27% of all dyslipidemic patients (and 40.7% of the recognized dyslipidemic patients) were treated with lipid-lowering medications, and 11.1% of all dyslipidemic patients (41.4% of the patients treated with lipid-lowering drugs) achieved their LDL-C treatment goals. In conclusion, 80.3% of patients in the sample with dyslipidemia went undiagnosed, un-treated or under-treated.

[Toxic megacolon--surgical point of view]. / Toxisches Megakolon--Chirurgische Sicht.

Toxic megacolon is an infrequent, but potentially fatal complication of a fulminant colitis. Toxic colonic dilatation, also caused by ischaemic or infectious inflammation like pseudomembranous colitis, mostly occur in patients with inflammatory bowel disease. Toxic mega-colon is defined as segmental or total colonic distension of >6 cm with the presence of clinical signs of acute colitis and systemic toxicity. Because of the associated high morbidity and mortality the early diagnosis and the management play an important role. The free perforation means a fourfold increase in the mortalitiy of the acute colitis. Recognition of toxic megacolon is underlaying by x-ray of the abdomen with colonic distension and a lack of haustral pattern. Accompanying distension of the small bowel can predict the development of the disease. CT scanning shows a diffuse wall thickening, pericolic inflammation and abnormal haustral pattern and can also detect subclinical perforation or abscesses. The management of toxic megacolon should be with intravenous parenteral nutrition, adaequate supplementation of intravenous fluids and correction of electrolytes abnormalities and the therapy of colitis with corticosteroids. Antibiotics are indicated in infectious disease or bacteriemia and also in colonic perforation. Surgical intervention is indicated by the onset of signs of progression of the disease and complications as perforation, uncontrollable bleeding or distension. The surgical procedure of choice is colectomy and ileostomy. The mortality and morbidity was decreased by avoiding rectal excision. The rectum is closed as a Hartmann's procedure or a mucous fistula is created. A secondary ileoanal pouch can be created at a later date. The interdisciplinary approach with optimal timing of surgical intervention can decrease the morbidity and mortality of toxic megacolon.

[Cardiovascular high-risk constellations in primary care. DETECT Study 2003]. / Kardiovaskuläre Hochrisikokonstellationen in der primärärztlichen Versorgung. DETECT-Studie 2003

DETECT is a nationwide epidemiological cross-sectional and longitudinal study program in a random probability sample of 3,795 primary care settings (response rate: 60.2%). Based on a target day total assessment of n=55,518 consecutive patients (RR 93.5%) in these settings all patients underwent standardized diagnostic assessment, using self-reporting, clinical interview and laboratory measures. DETECT aims at describing the point prevalence and comorbidity of coronary heart disease (CHD), hyperlipidaemia, arterial hypertension and diabetes mellitus and at identifying the behavioural, clinical, laboratory and psychological risk factors associated with these conditions. A random subset of patients (n=7,519) also completed an extensive standardized laboratory screening program and a 12-month follow-up investigation. Findings reveal a high prevalence of hypertension (36.3%), dyslipidaemia (29.1%), diabetes mellitus (14.6%) and CHD (12.4%) in primary care as well as their close association among each other. The study describes for the first time in greater detail the prevalence of specific disorders and the frequency of high-risk constellations in primary care and allows for the evaluation of various risk scores.

[Surgical therapy of complicated inflammatory bowel disease]. / Chirurgische Therapie der Komplikationen der chronisch entzündlichen Darmerkrankungen.

The etiology of chronic inflammatoric bowel disease is unknown, conservative treatment will be reduced to the management of immunologic and inflammatoric reaction. The large majority of patients affected with Crohn's disease and also nearly 50% of patients with ulcerous colitis require surgery during their clinical history. The indication for surgery is a balance between the severity and the complications of the disease and the potential disadvantages of surgery. For surgical therapy the differentiation of Crohn's disease and ulcerous colitis is essential because of the differentiated character of both diseases. In Crohn's disease surgical therapy will be performed by the management of Crohn's specific complications like stenosis, fistula, and abscess by bowel preserveration. Limited resection and/or strictureplasty do not influence morbidity and rate and also time of recurrence. Ulcerous colitis can be cured when the colorectal mucosa will be removed totally by radical surgery, i.e. restorative proctocolectomy. The satisfactory outcome in 70 to 90% of patients with a cumulative failure rate of 10 to 15% over a 10-year-period improves the quality of life.

Cardiovascular risk factors in primary care: methods and baseline prevalence rates--the DETECT program.

OBJECTIVES: DETECT is an epidemiological study in primary care to examine (a) the prevalence rates and comorbidity of diabetes mellitus, hypertension, hyperlipidaemia and coronary heart disease (CHD), and associated conditions; (b) the frequency of behavioural and clinical risk factors for onset and progression; (c) the 12-month course and outcome; and (d) the met and unmet needs for these patients. METHODS: Three-stage, cross-sectional clinical-epidemiological study with a prospective-longitudinal component in a nationally representative sample of N = 3795 primary care settings [response rate (RR): 60.2%] and N = 55518 patients (RR: 95.5%). Patients completed a standardized assessment, including questionnaires for patients and the physician and diagnostic screening measures (i.e. blood pressure, heart rate, body mass index and waist circumference assessments). A subsample of patients (N = 7519) also completed a standardized laboratory screening program and was followed-up after 12 months. Data were weighted to adjust for non-response, regional distribution and attrition. RESULTS: (1) Doctors and patients sample can be regarded as representative for primary care settings in Germany. (2) The clinician-rated point prevalence of hypertension is highest (35.5%), followed by hyperlipidaemia (29.1%), diabetes (14.1%) and CHD (12.1%); prevalence rates of each disorder as well as their co-incidence rates increase markedly with age. (3) The vast majority (78%) of all patients revealed multiple (3+) behavioural and clinical risk factors. CONCLUSION: The findings of DETECT underline the considerable burden for primary care doctors in managing a highly morbid patient population, with predominantly complex risk factor constellations, in routine care. Our data provide, in unprecedented detail, a basis for calculating age-, gender- and risk-group-adjusted risk-factor profiles in routine care.

[Preoperative chemoradiation in esophageal cancer: experience of a single center in 102 patients]. / Präoperative Radio-Chemotherapie beim Osophaguskarzinom: Erfahrungen eines Zentrums mit 102 Patienten.

The (dis-)advantages of preoperative chemoradiation in patients with esophageal cancer (EC) are still controversial as data are lacking showing a clear cut benefit. Therefore, data of neoadjuvant therapy of our hospital have been analyzed. Since 1994 102 patients with an EC (33 % adenocarcinoma, 67 % squamous cell cancer, scc) were operated after receiving preoperative chemoradiation (36 Gy radiation, 1.8 Gy/day for 4 weeks, 500 mg/m (2) 5-FU for 4 weeks and 20 mg/m (2) Cisplatin, day 1-5, week 1 and 4). Operation was performed usually 8-10 weeks after treatment start. In 11.7 % of patients with an adenocarcinoma a complete pathological response (CR, pT0N0M0) was observed and a pT0 stage in 20.6 %. 38.2 % of these patients were staged as pN0. Postoperative morbidity was observed in 66 % (anastomotic leakage in 20 %, recurrent nerve palsy in 23 %). In-hospital mortality was 5.9 %. 5-year survival was calculated as 30.5 %, in patients wit a CR 66 %.26.5 % of patients with a scc revealed a CR. However no effect at all was observed in 32 % of these patients. 56 % were staged as pN0. Postoperative morbidity was observed in 87 % (anastomotic leakage in 16 %, recurrent nerve palsy in 32 %). In-hospital mortality was 11.8 %. 5-year survival was calculated as 19.2 %, in patients with a CR 45 %. The impact of pN stage was significant (p = 0.0052). These results underline the benefit of neoadjuvant therapy in patients with a CR. Further on, a pN0 stage is an important prognostic indicator. However, it remains open, whether neoadjuvant therapy leads to a downstaging of lymph node involvement, as histological confirmation in clinically positive lymph node is seldom performed prospectively.

The use of atorvastatin treatment in usual care environments: pooled analysis of six prospective, observational studies in 90,535 patients.

OBJECTIVE: We investigated the pattern of use as well as the efficacy and safety of atorvastatin in unselected inpatients and outpatients in routine clinical practice in Germany. DESIGN: Six prospective, observational studies with a similar design were pooled. The studies lasted for up to 12 weeks and data from 90,535 patients (7,287 inpatients, 83,248 outpatients) were collected. The studies were performed in Germany in 2000 and 2001. Hospital or office-based physicians selected hyperlipemic patients with or without coronary heart disease (CHD) for once daily treatment with atorvastatin. Information on demographics, atorvastatin dosage, concomitant medication, concomitant diseases, cardiovascular risk factors, lipid profile as well as adverse events (AEs) and serious adverse events (SAEs) were obtained at 2-3 visits and descriptively analyzed. MAIN OUTCOME MEASURES: Absolute and relative changes in lipid parameters, percentage of patients with low-density lipoprotein cholesterol (LDL-C) values within target ranges according to the National Cholesterol Education Program (NCEP) criteria, and frequencies of AEs. RESULTS: On average, patients were treated for 22.4 days (inpatients) and 106.0 days (outpatients), respectively. The overall mean atorvastatin dose of 14.4 mg/day was well tolerated by a heterogeneous patient population with a variety of concomitant diseases and medications. Overall, 0.8% of patients suffered from one or more AEs, 0.6% were considered as treatment-related. The corresponding figures for SAEs and treatment-related SAEs were 0.1% (131 patients) and 0.01% (13 patients), respectively. Subgroup analyses did not reveal a particular safety concern in any subgroup. In total, 99% of patients judged the tolerability of atorvastatin as very good or good. The mean percentages of reduction in LDL-C at the final visit ranged between 24.8% and 28.5%. Overall, 26.3% of patients reached the NCEP LDL-C goal compared to 4.9% at baseline. Inpatients achieved the target range for LDL-C more frequently than outpatients (35.3% vs 25.6%). An underuse of atorvastatin titration in clinical practice in Germany was apparent, particularly in outpatients. CONCLUSIONS: The use of atorvastatin in usual care environments is effective and safe. There is a gap between treatment guidelines and clinical practice in Germany as reflected by the number of patients outside the target range for LDL-C. A major opportunity exists to increase the number of patients who achieve LDL-C target ranges by appropriate dose titration and/or giving patients a higher initial dose. Available guidelines need to be implemented more stringently.

Diabetes and cardiovascular risk evaluation and management in primary care: progress and unresolved issues - rationale for a nationwide primary care project in Germany.

This review highlights established and more recently recognized risk factors for coronary heart disease (CHD) relevant for patients seen in primary care, emphasizing the key role of diabetes mellitus type 2. Recent trends in risk factor research as well as current methods of risk stratification, and new systemic markers are discussed. Beyond the need for more forceful public health strategies to improve early recognition and intervention, the necessity of an integrated comprehensive investigation of the overall characteristics of cardiovascular disease, especially in primary care patients as a prerequisite for future concerted actions is pointed out. Based on this, a large-scale epidemiological investigation focusing on CHD and diabetes in the primary care sector is suggested.

Complete remission of Crohn's disease after high-dose cyclophosphamide and autologous stem cell transplantation.

In a 36-year-old male with ileocolic Crohn's disease (CD) no long-lasting remission was obtained by treatment with corticosteroids, mesalazine, azathioprine and antibiotics. Surgical interventions due to relapsing fistulae and abscesses resulted in the removal of >1.5 m of small bowel and left only 40 cm of large bowel. In July 2000, a new fistula and abscess developed. The combination of corticosteroids, mesalazine, ciprofloxacin, metronidazol, azathioprine, formula diet and anti-TNF-alpha antibody largely reduced clinical activity, and resection of fistula and abscess were successful. Despite clinical remission, histology showed activity in the small bowel and the colon. In March 2001, stem cell mobilization chemotherapy with cyclophosphamide was performed. It induced an endoscopic remission for 9 months, which was maintained on azathioprine and corticosteroids. After relapse, in March 2002, high-dose chemotherapy with cyclophosphamide and reinfusion of T-cell-depleted autologous peripheral CD34+ blood stem cells were performed. This led to a complete clinical, endoscopical and histological remission for 9 months without any treatment. Thereafter, endoscopy showed initial aphthous lesions with minimal histological signs of inflammation. The patient is asymptomatic, but low-dose prednisolone and methotrexate are prophylactically given. Immunoablative chemotherapy followed by autologous peripheral blood stem cell transplantation may be a beneficial therapeutic option in complicated refractory CD.

[Lesions around the rectum. Diagnosing and treatment abscesses and fistulas]. / Läsionen rund ums Rektum. Wie Sie Abszesse und Fisteln diagnostizieren und behandeln.

Anorectal abscesses and fistulas are among the most common anorectal lesions. They represent different phases of one and the same condition, the abscess being the acute manifestation, the fistula the chronic form. In the event of a strong suspicion, rapid referral to hospital, preferably one specializing in proctology, is indicated. The treatment of choice of both abscesses and fistulas is surgery. Abscesses are widely incised and decompressed. Fistulas showing signs of fresh secretion may be treated initially by the insertion of a thread, and subsequently undergo definitive surgical treatment. The surgical procedure is determined by the site of the fistula. Attendant risks include recurrence and incontinence. When fistulas occur in Crohn's disease, the indication for surgical treatment must be stringently applied. In the absence of complications, postoperative healing of the wound should be checked regularly.

Sphincter-saving treatment in epidermoid anal cancer: cooperative analysis of 142 patients in five German university surgical centers.

Five southern German university centers cooperated in comparing the effect of surgical vs. nonsurgical therapy strategies on survival and sphincter preservation in the treatment of anal cancer. A standardized questionnaire was used to evaluate retrospectively (mean follow-up 30 months) treatment strategy and outcome (survival, colostomy rate, colostomy-free survival) in patients treated between 1987 and 1996. Of the 142 patients 65% had squamous cell, 20% basaloid, 6% adeno-, and 1% undifferentiated carcinoma (8% histology not recorded); 9% were classified in UICC stage I, 37% in stage II, 25% in stage III, and 4% in stage IV (25% not recorded). Primary treatment consisted of local excision (10%), excision plus radio- and/or chemotherapy (17%), radiotherapy (20%), radiochemotherapy (28%), or colostomy with or without resection, radiotherapy, and chemotherapy (23%). We observed no difference between these treatment groups in overall (P = 0.43) or colostomy-free survival (P = 0.14, log-rank). Primary colostomy was prevented in 77% of cases and decreased over the years. Mean overall survival (in months) was 42 in stage I, 38 in stage II, and 25 in stage III (P = 0.0013); mean colostomy-free survival was 36 in stage I, 26 in stage II, and 16 in stage III (P = 0.0021, log-rank). Outcome was not significantly related to therapeutic strategy (surgery or radio-chemotherapy. Primary surgical and nonsurgical strategies in treating anal cancer thus produced similar results, although radiochemotherapy is usually recommended for sphincter-endangering anal cancer. Challenges to be met in the future include the prevention of metastasis and long-term preservation of anal sphincter function.
