Journal article (peer-reviewed)abstract
- Radiotherapy is effective in the treatment of cancer but also causes damage to non-cancerous tissue. Pelvic radiotherapy may produce chronic and debilitating bowel symptoms, yet the underlying pathophysiology is still undefined. Most notably, although pelvic radiotherapy causes an acute intestinal inflammation there is no consensus on whether the late-phase pathophysiology contains an inflammatory component or not. To address this knowledge gap, we examined the potential presence of a chronic inflammation in mucosal biopsies from irradiated pelvic cancer survivors.We biopsied 24 cancer survivors two to 20 years after pelvic radiotherapy, and four non-irradiated controls. Using tandem mass tag (TMT) mass spectrometry and mRNA sequencing (mRNA-seq), we charted proteomic and transcriptomic profiles of the mucosal tissue previously exposed to a high or a low/no dose of radiation. Changes in the immune cell populations were determined with flow cytometry. The integrity of the protective mucus layers were determined by permeability analysis and 16S rRNA bacterial detection.942 proteins were differentially expressed in mucosa previously exposed to a high radiation dose compared to a low radiation dose. The data suggested a chronic low-grade inflammation with neutrophil activity, which was confirmed by mRNA-seq and flow cytometry and further supported by findings of a weakened mucus barrier with bacterial infiltration.Our results challenge the idea that pelvic radiotherapy causes an acute intestinal inflammation that either heals or turns fibrotic without progression to chronic inflammation. This provides a rationale for exploring novel strategies to mitigate chronic bowel symptoms in pelvic cancer survivors.This study was supported by the King Gustav V Jubilee Clinic Cancer Foundation (CB), The Adlerbertska Research Foundation (CB), The Swedish Cancer Society (GS), The Swedish State under the ALF agreement (GS and CB), Mary von Sydow's foundation (MA and VP).

Early and individualized cancer rehabilitation important : Tidig och individualiserad cancerrehabilitering viktig
- 2015
-
In: Läkartidningen. - 0023-7205. ; 112
-
Journal article (peer-reviewed)abstract
- Survivors of gynecological cancer experience physical, psychological and existential consequences. Late gastrointestinal and urinary bladder symptoms, sexual dysfunction, including underlying physical and relational aspects, as well as lymphedema and fatigue, are common complaints. This may lead to reduced quality of life and social functioning and cancer rehabilitation is needed. Cancer rehabilitation, focusing on the individual cancer survivor and her specific needs, starting at diagnosis and continuing throughout cancer treatment and at follow-ups, is necessary.

Serum Androgen Levels and Sexual Function Before and One Year After Treatment of Uterine Cervical Cancer: A Pilot Study.

- Radiotherapy or radical hysterectomy with salpingo-oophorectomy (SOE) as treatment for uterine cervical cancer causes estrogen deprivation in premenopausal women. The effects on androgen production have rarely been examined but could be relevant for survivors of cervical cancer because insufficiency has been associated with low sexual function.

Anti-Müllerian hormone in premenopausal women following treatment of uterine cervical cancer.

In: Acta obstetricia et gynecologica Scandinavica. - : Wiley. - 1600-0412 .- 0001-6349. ; 93:9, s. 949-53

Journal article (peer-reviewed)abstract
- In this longitudinal study we prospectively enrolled 32 premenopausal women (ages 23-44years) with stage I-III uterine cervical cancer undergoing surgery and/or chemoradiation. Serum levels of anti-Müllerian hormone, follicle-stimulating hormone and estradiol were examined at baseline and 1year after treatment. As expected, serum anti-Müllerian hormone was undetectable after salpingo-oophorectomy or chemoradiation. After radical hysterectomy and pelvic lymphadenectomy with ovarian preservation serum anti-Müllerian hormone declined from a mean value of 2.0±1.4μg/L to 1.1±0.8μg/L (p=0.01), representing a 45% reduction, whereas there was no significant change in serum levels of follicle-stimulating hormone and estradiol. This implies that ovarian function may be affected not only by castrating treatment but also by radical hysterectomy with ovarian preservation. The risk of premature menopause and the potential need of hormone replacement therapy among these women may be overlooked since they no longer menstruate.

Reduced vaginal elasticity, reduced lubrication, and deep and superficial dyspareunia in irradiated gynecological cancer survivors
- 2015
-
In: Acta Oncologica. - : Taylor & Francis. - 0284-186X .- 1651-226X. ; 54:5, s. 772-779

Journal article (peer-reviewed)abstract
- Purpose. The purpose of this study was to examine whether or not vaginal elasticity or lack of lubrication is associated with deep or superficial dyspareunia. We investigated gynecological cancer survivors treated with radiation therapy. Methods. In a population-based study with 616 women answering a questionnaire (participation rate 78%) and who were treated with radiotherapy for gynecological cancer, we analyzed information from 243 women (39%) who reported that they had had intercourse during the previous six months. Analyses included log-binomial regression (relative risks) and multiple imputations by chained equations in combination with Bayesian Model Averaging, yielding a posterior probability value. Age range of this cancer recurrent-free group of women was 29-80. Results. Dyspareunia affected 164 of 243 of the women (67%). One hundred thirty-four women (55%) reported superficial pain, 97 women (40%) reported deep pain, and 87 women (36%) reported both types of dyspareunia. The relative risk (RR) of deep dyspareunia was 1.87 (CI 1.41-2.49) with impaired vaginal elasticity compared to normal vaginal elasticity. Age and lower abdominal swelling were separate risk factors for deep dyspareunia. However, effects remain after adjusting for these factors. Conclusion. The relative risk of deep dyspareunia was almost twice as high with impaired vaginal elasticity compared to normal vaginal elasticity. If we wish to treat or even prevent deep dyspareunia in women with gynecological cancer, we may use our knowledge of the pathophysiology of deep dyspareunia and increasingly provide dilators together with instructions on how to use them for stretching exercises in order to retain vaginal elasticity. Results highlight the need for studies with more precise questions distinguishing superficial from deep dyspareunia so that in the future we may be able to primarily try to avoid reduced vaginal elasticity and secondarily reduce the symptoms.

A comparison of two imaging modalities for detecting lymphatic nodal spread in radiochemotherapy of locally advanced cervical cancer
- 2018

In: Physics and Imaging in Radiation Oncology. - : Elsevier BV. - 2405-6316. ; 8, s. 33-37

Journal article (peer-reviewed)abstract
- Background and purpose: In uterine cervical cancer tumour spread reaching the para-aortic lymph nodes is the most significant independent pre-treatment predictor of progression-free survival. When introducing [18F] fluorodeoxyglucose-positron emission tomography (FDG-PET)/computed tomography (CT) in our clinic for patients with advanced cervical cancer planned for definitive radiochemotherapy, the purpose of this study was to quantify to what extent the added information lead to changes in radiotherapy planning. Material and methods: We included 25 consecutive patients with cervical cancer stages IB2 – IIIB planned for definitive radiochemotherapy between November 2010 and May 2012. The patients were examined both with magnetic resonance imaging (MRI) and FDG-PET/CT before treatment and after four weeks of treatment. Results: In 11/24 (46%) of the patients the FDG-PET/CT before treatment provided additional diagnostic information leading to changes in treatment planning compared to information from MRI. Seven of these eleven patients (64%) were alive and without evidence of disease at four-year follow-up. The MRI detected pelvic tumour spread not seen on the FDG-PET/CT in 2/24 patients. The disease-free four-year survival was 59%. Conclusions: Additional diagnostic information from FDG-PET/CT changed treatment strategy in almost half of the patients and may have increased chances of survival in this limited group of patients with locally advanced uterine cervical cancer. We recommend both modalities for nodal detection.
