- Background. Carcinosarcomas are a highly malignant type of endometrial carcinomas where extra uterine spread and recurrences are frequent. There is no consensus regarding the best treatment of this group of malignancies. Material and methods. In a complete geographic series of 322 cases of primary uterine carcinosarcomas prophylactic pelvic irradiation and/or chemotherapy was used as postoperative treatment in the majority of the cases. Vaginal brachytherapy was also added as a boost. The primary surgery was extended hysterectomy in 23 cases (10%), and simple hysterectomy in 220 cases (90%). In 46 cases (14%) no major surgery was possible. Results. In the complete series 123 recurrences (38%) were recorded. Locoregional recurrences (11%) and distant recurrences (28%) were most frequent. Type and extent of surgery was not associated with the risk of tumor recurrence. Extended surgery did not reduce the risk of local and regional recurrences. In the complete series, the five-year overall survival rate was 30% and the recurrence-free survival (RFS) rate was 27%. The five-year pelvic disease control was 82% in stage I, 68% in stage II, and 76% for more advanced stages. The five-year locoregional RFS rate was 63% for patients treated with surgery alone, 68% after addition of adjuvant chemotherapy, 86% after adjuvant radiotherapy, and 95% after combined chemotherapy and radiotherapy. Conclusion. Radiotherapy seems to be the most important constituent of the adjuvant therapy. Serious late tissue reactions, requiring surgery, from the bladder and intestine occurred in 2.5% of the irradiated cases. The death of three patients could be related to radiotherapy and of four patients due to the cytotoxic treatment. This population-based series may serve as a baseline for improvements by, e.g. standard care programs and referral to a few specialist centers for this rare and serious disease.

- Operationsresultat redovisas för män opererade med radikal prostatektomi – öppen kirurgi jämfört med robotassisterad laparaskopi – under 2002–2006 vid Karolinska universitetssjukhuset, Solna. Män som följdes under minst 1 år besvarade enkätfrågor; 768 robotkirurgiska och 411 öppenkirurgiska operationer utvärderades. Under perioden minskade andelen män med positiv resektionsrand från 37 procent till 22 procent och med erektil dysfunktion från 66 procent till 60 procent. Andelen optimala operationsresultat (»trifecta«) ökade från 19 procent till 28 procent. Vi har inte hittat några indikationer på att införandet av robotkirurgi har försämrat situationen för män diagnostiserade med prostatacancer. Vi kan inte avgöra om de positiva operationsresultaten skulle ha blivit bättre eller sämre om ett utvecklingsprogram för öppen radikal prostatektomi i stället initierats. En nationell studie, LAPPRO, avseende effekterna av de två operationsformerna pågår.

- Purpose. The aim of this study was to investigate what bowel organ and delivered dose levels are most relevant for the development of 'emptying of all stools into clothing without forewarning' so that the related dose-responses could be derived as an aid in avoiding this distressing symptom in the future. Material and methods. Of the 77 gynecological cancer survivors treated with radiotherapy (RT) for gynecological cancer, 13 developed the symptom. The survivors were treated between 1991 and 2003. The anal-sphincter region, the rectum, the sigmoid and the small intestines were all delineated and the dose-volume histograms were exported for each patient. The dose-volume parameters were estimated fitting the data to the Relative Seriality (RS), the Lyman and the generalized Equivalent Uniform Dose (gEUD) model. Results. The dose-response parameters for all three models and four organs at risk (OARs) were estimated. The data from the sigmoid fits the studied models best: D50 was 58.8 and 59.5 Gy (RS, Lyman), γ50 was 1.60 and 1.57 (RS, Lyman), s was 0.32, n was 0.13 and a was 7.7 (RS, Lyman, gEUD). The estimated volume parameters indicate that the investigated OARs behave serially for this endpoint. Our results for the three models studied indicate that they have the same predictive power (similar LL values) for the symptom as a function of the dose for all investigated OARs. Conclusions. In our study, the anal-sphincter region and sigmoid fit our data best, but all OARs were found to have steep dose-responses for 'emptying of all stools into clothing without forewarning' and thus, the outcome can be predicted with an NTCP model. In addition, the dose to the four studied OARs may be considered when minimizing the risk of the symptom.

- PURPOSE: To supplement previous findings that the absorbed dose of ionizing radiation to the anal sphincter or lower rectum affects the occurrence of fecal leakage among irradiated prostate-cancer survivors. We also wanted to determine whether anatomically defining the anal-sphincter region as the organ at risk could increase the degree of evidence underlying clinical guidelines for restriction doses to eliminate this excess risk. METHODS AND MATERIALS: We identified 985 men irradiated for prostate cancer between 1993 and 2006. In 2008, we assessed long-term gastrointestinal symptoms among these men using a study-specific questionnaire. We restrict the analysis to the 414 men who had been treated with external beam radiation therapy only (no brachytherapy) to a total dose of 70 Gy in 2-Gy daily fractions to the prostate or postoperative prostatic region. On reconstructed original radiation therapy dose plans, we delineated the anal-sphincter region as an organ at risk. RESULTS: We found that the prevalence of long-term fecal leakage at least once per month was strongly correlated with the mean dose to the anal-sphincter region. Examining different dose intervals, we found a large increase at 40 Gy; ≥40 Gy compared with <40 Gy gave a prevalence ratio of 3.8 (95% confidence interval 1.6-8.6). CONCLUSIONS: This long-term study shows that mean absorbed dose to the anal-sphincter region is associated with the occurrence of long-term fecal leakage among irradiated prostate-cancer survivors; delineating the anal-sphincter region separately from the rectum and applying a restriction of a mean dose <40 Gy will, according to our data, reduce the risk considerably.

- Purpose. To study if partnership modifies the effect of gastrointestinal symptoms on quality of life after radiation therapy for prostate cancer. Material and methods. Using a study-specific questionnaire we conducted a cross-sectional follow-up of the occurrence gastrointestinal symptoms and quality of life after radiation therapy for prostate cancer. We obtained information from 874 prostate cancer survivors treated with radiation therapy at the Sahlgrenska University Hospital, Sweden between 1994 and 2006. In this paper we describe how partnership status affects the association between gastrointestinal symptoms and quality of life. Results. We found that unpartnered men with gastrointestinal symptoms reported a lower quality of life than unpartnered men without such symptoms. Unpartnered men with symptoms had an excess risk of low quality of life compared with unpartnered men without symptoms for those experiencing altered composition of stools, prevalence ratio 3.8 (95% CI 1.1-13.1), leakage, 3.6 (1.3-10.1), sensory bowel symptoms, 4.5 (1.6-12.8), and for urgency, 4.2 (1.2-15.1). We also found that unpartnered men with symptoms had an excess risk of low quality of life compared with partnered men with symptoms for those experiencing altered composition of stools, prevalence ratio 2.9 (95% CI 1.4-5.8), leakage 2.8 (1.2-6.4), sensory bowel symptoms 3.4 (1.5-7.4), urgency 2.6 (1.2-5.8), and for any gastrointestinal symptom 2.5 (1.3-4.9). Conclusion. Unpartnered men may represent a group that is specifically vulnerable to the distressful effects of gastrointestinal symptoms after radiation therapy for prostate cancer.

- Purpose This study was conducted to investigate the association of long-term gastrointestinal and urinary symptoms with perceived fecal or urine body odor after radiation therapy for prostate cancer and its effect on survivors’ quality of life. Methods We used a study-specific questionnaire to measure the occurrence of long-term gastrointestinal and urinary symptoms, the perception of fecal or urine body odor, and quality of life (QoL) 2 to 14 years after radiation therapy for prostate cancer. The questionnaire was sent to 895 eligible survivors who assessed symptom occurrence and QoL in the previous 6 months. Results We received a filled-in questionnaire from 874 (89 %) men. For the long-term gastrointestinal symptoms, 11/13 were associated with the perception of fecal body odor. For the long-term urinary symptoms, 11/11 were associated with the perception of urine body odor. Men who perceived fecal or urine body odor had a lower quality of life, a lower physical health, and more frequent feelings of depression compared with those who did perceive such body odor. Conclusion Long-term gastrointestinal and urinary symptoms after prostate irradiation are associated with the perception of fecal or urine body odor leading to a reduced quality of life. Implications for cancer survivors Disabling body odor after pelvic irradiation needs to be acknowledged in the clinic. Interventions to prevent long-term symptoms may serve the benefit of avoiding fecal or urine body odor after radiation therapy for prostate cancer.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND PURPOSE: Tobacco smoking can cause vascular injury, tissue hypoxia and fibrosis as can ionizing radiation. However, we do not know if tobacco smoking increases the risk of long-term side effects after radiotherapy for prostate cancer. METHODS: We identified 985 men treated with radiotherapy for prostate cancer between 1993 and 2006. In 2008, long-lasting symptoms appearing after radiotherapy for prostate cancer were assessed through a study-specific questionnaire as were smoking habits and demographic factors of all these men. In the questionnaire the prostate-cancer survivors were asked to report symptom occurrence the previous six months. RESULTS: We obtained information on tobacco smoking from 836 of the 985 prostate-cancer survivors with a median time to follow-up of six years (range 2-14years). The prevalence ratio of defecation urgency among current smokers compared to never smokers was 1.6 (95% CI 1.2-2.2). Corresponding prevalence ratio for diarrhea was 2.8 (95% CI 1.2-6.5), the sensation of bowel not completely emptied after defecation 2.1 (95% CI 1.3-3.3) and for sudden emptying of all stools into clothing without forewarning 4.7 (95% CI 2.3-9.7). CONCLUSION: Tobacco smoking among prostate-cancer survivors treated with radiotherapy increases the risk of certain long-lasting symptoms from the bowel and anal-sphincter region.

- ObjectiveThe focus of this study was on the impact of spousal loss on the development of chronic pain thereafter. More specifically, the aim was to investigate the effect of experiencing low preparedness before a wife's death and the widower's chronic pain 4-5 years after loss. MethodsIn a population-based study in the years 2004-2005, anonymous questionnaires were sent out to 907 men in Sweden who had lost a wife to cancer in 2000 and 2001. The questionnaires contained questions on the man's preparedness for his wife's death and his physical and psychological health at follow-up. ResultsAltogether, 691 out of 907 questionnaires were retrieved (76%). Younger widowers (38-61 years old) with a low degree of preparedness for their wife's death had an increased risk of experiencing symptoms of chronic pain (odds ratio 6.67; 2.49-17.82) 4-5 years after loss. The same results did not apply for older widowers (62-80 years old) (odds ratio 0.81; 0.32-2.05). Widowers who experienced chronic pain were at an increased risk for psychological morbidity, depression (relative risk [RR] 2.21; 1.31-3.74), anxiety (RR 2.11; 1.33-3.37), and sleep disorders (RR 2.19; 1.30-3.69). ConclusionOur data suggest that low preparedness for a wife's death may increase risk of chronic pain among younger widowers 4-5 years after loss. In addition, we found comorbidity between psychological symptoms and chronic pain among widowers. These findings call for studies on possible mechanisms in the association between low preparedness and morbidity and on how to increase preparedness for a wife's death to cancer.
