Occult Breast Cancer due to Multiple Calcified Hamartomas in a Patient with Cowden Syndrome.

Cowden syndrome (CS) is an autosomal dominant disorder characterized by presence of multiple hamartomas, and other benign and malignant abnormalities of the breasts, skin, thyroid, endometrium, gastrointestinal tract, and central nervous system. Hamartomas are benign, developmentally disorganized tumors that can develop in any of the above mentioned organs. The presence of massive calcifications in the breasts in very young women is an indication to perform a breast MRI to exclude a neoplasm since, like in the current case report, presence of breast calcifications may obscure a neoplasm. Although fibrocystic disease and cooccurrence of fibrocystic disease and breast cancer are much more common than CS, the presence of massive calcifications in the breasts of very young women should elicit the possibility of an underlying genetic disease. Furthermore, breast cancer and macrocephaly are considered major criteria for the diagnosis of CS and the combination of both is enough to establish the clinical diagnosis of this entity. Fibrocystic disease of the breasts and multinodular goiter are minor criteria. Family history is also important for the diagnosis of (any) hereditary disease.

Economic evaluation of four follow-up strategies after curative treatment for breast cancer: results of an RCT.

BACKGROUND: An economic evaluation was performed alongside a randomised controlled trial (ISRCTN 74071417) investigating the cost-effectiveness of nurse-led telephone follow-up instead of hospital visits, and of a short educational group programme (EGP) in the first year after breast cancer treatment. METHOD: This economic evaluation (n = 299) compared the one-year costs and the effects of four follow-up strategies: (1) hospital follow-up; (2) nurse-led telephone follow-up; (3) hospital follow-up plus EGP; and (4) nurse-led telephone follow-up plus EGP. Costs were measured using cost diaries and hospital registrations. Quality-adjusted life years (QALYs) were measured using the EQ-5D. Outcomes were expressed in incremental cost-effectiveness ratios (ICERs) and cost-effectiveness acceptability curves. RESULTS: Hospital follow-up plus EGP yielded most QALYs (0.776), but also incurred the highest mean annual costs (€4914). The ICER of this strategy versus the next best alternative, nurse-led telephone follow-up plus EGP (0.772 QALYs and €3971), amounted to €235.750/QALY. Hospital and telephone follow-up without EGP both incurred higher costs and less QALYs than telephone follow-up plus EGP and were judged inferior. Hospital follow-up plus EGP was not considered cost-effective, therefore, telephone follow-up plus EGP was the preferred strategy. The probability of telephone follow-up plus EGP being cost-effective ranged from 49% to 62% for different QALY threshold values. Secondary and sensitivity analyses showed that results were robust. CONCLUSION: Nurse-led telephone follow-up plus EGP seems an appropriate and cost-effective alternative to hospital follow-up for breast cancer patients during their first year after treatment.

Nurse-led telephone follow-up and an educational group programme after breast cancer treatment: results of a 2 × 2 randomised controlled trial.

OBJECTIVE: To investigate whether frequent hospital follow-up in the first year after breast cancer treatment might partly be replaced by nurse-led telephone follow-up without deteriorating health-related quality of life (HRQoL), and whether a short educational group programme (EGP) would enhance HRQoL. PATIENTS AND METHODS: A multicentre pragmatic randomised controlled trial (RCT) with a 2×2 factorial design was performed among 320 breast cancer patients who were treated with curative intent. Participants were randomised to follow-up care as usual (3-monthly outpatient clinic visits), nurse-led telephone follow-up, or the former strategies combined with an educational group programme. The primary outcome for both interventions was HRQoL, measured by EORTC QLQ-C30. Secondary outcomes were role and emotional functioning and feelings of control and anxiety. RESULTS: Data of 299 patients were available for evaluation. There was no significant difference in HRQoL between nurse-led telephone and hospital follow-up at 12 months after treatment (p = 0.42; 95% confidence interval (CI) for difference: -1.93-4.64) and neither between follow-up with or without EGP (p = 0.86; 95% CI for difference: -3.59-3.00). Furthermore, no differences between the intervention groups and their corresponding control groups were found in role and emotional functioning, and feelings of control and anxiety (all p-values > 0.05). CONCLUSION: Replacement of most hospital follow-up visits in the first year after breast cancer treatment by nurse-led telephone follow-up does not impede patient outcomes. Hence, nurse-led telephone follow-up seems an appropriate way to reduce clinic visits and represents an accepted alternative strategy. An EGP does not unequivocally affect positive HRQoL outcomes.

A patient-centred instrument for assessment of quality of breast cancer care: results of a pilot questionnaire.

BACKGROUND: In several breast cancer research environments, there was a need to develop a questionnaire that would (1) provide data on how breast cancer patients experience healthcare services, (2) address issues corresponding with patients' needs and expectations and (3) produce useful data for quality assessment and improvement projects aimed at breast cancer care. This article describes the first part of the quantitative process of item selection, instrument construction and optimisation based on the results of a pilot questionnaire. METHODS: Based on qualitative research, a pilot questionnaire with items formulated as "performance" and "importance" statements was developed and sent to all breast cancer patients operated on in the previous 3-15 months in five participating hospitals. Reduction criteria, exploratory factor analysis and reliability analysis were used as part of the process of instrument optimisation. RESULTS: Of the 637 questionnaires sent out, 299 (47%) were returned and 276 (43%) were used for analyses. Out of the 72 quality items included in the pilot questionnaire, 42 items did not meet the inclusion criteria for the revised version. The remaining items refer to the factors patient education regarding aspects related to postoperative treatment, services by the breast nurse, services by the surgeon, patient education regarding activities at home and patient education regarding aspects related to preoperative treatment (Cronbach α = 0.70-0.89). CONCLUSIONS: In this study, the number of items to be included in the self-administered questionnaire was reduced. The resulting set of items that determines patients' perceptions on quality of breast cancer care is easy to complete and enables anonymous responses. Further research can be aimed at establishing the reliability of the current questionnaire.

Patients' opinions on quality of care before and after implementation of a short stay programme following breast cancer surgery.

PURPOSE: To assess breast cancer patients' opinions on quality of care during an implementation study on short hospital stay, and to formulate patient inspired targets for further quality improvement based on results of the QUOTE (Quality of Care Through the Patients' Eyes) breast cancer instrument. RESULTS: Quality of patient education regarding activities at home was in need of improvement in both measurements. Quality of services delivered by the surgeon improved somewhat after implementation. Although quality of waiting and process times improved after implementation, there was still room for further improvement on these aspects. CONCLUSION: A breast cancer care programme in short stay was introduced while, on average, preserving quality of care as perceived by the patient. However, aspects regarding education on drains, prosthesis, exercises after surgery, survival rates, and waiting and process times require continuing attention to enhance patients' assessment of quality of care.

Implementation of a short-stay programme after breast cancer surgery.

BACKGROUND: : Short-stay breast cancer surgery (24 h or day case) is not common practice in Europe. This before-after comparative study was carried out to test the feasibility of systematically implementing a care programme incorporating short-stay admission using strategies tailored to individual hospital needs, and to assess safety and facilitating factors. METHODS: : Patients with breast cancer from four Dutch hospitals participated. The intervention concerned the programme developed by the Maastricht University Medical Centre. This was implemented through local multidisciplinary meetings and educational outreach visits. RESULTS: : Of 421 eligible patients, 324 (77.0 per cent) gave consent to participate. The proportion of patients who had short-stay treatment increased from 45.3 per cent before to 82.2 per cent after implementation of the programme (P < 0.001). No increase was observed in the rate of complications, readmissions, reoperations or number of visits to the emergency department. Factors associated with an increased chance of short-stay treatment were: breast-conserving surgery, having children and being employed. Being aged over 64 years showed a trend towards a decreased chance. CONCLUSION: : Introducing a care programme incorporating short stay following breast cancer surgery in four hospitals was feasible and safe.

Breast MRI in clinically and mammographically occult breast cancer presenting with an axillary metastasis: a systematic review.

BACKGROUND: Axillary metastatic lymphadenopathy with no primary tumour identified in the breast on physical examination, mammography or ultrasound is referred to as occult breast cancer. The goal of this systematic review is to give an overview of the value and additional considerations of using breast MRI in occult breast cancer. METHODS: The databases of Pubmed, Embase, CINAHL and the Cochrane library were searched for studies addressing the use of breast MRI in occult breast cancer. Cross-referencing was used to find additional articles. RESULTS: 8 retrospective studies were included. Breast MRI can detect an otherwise occult breast cancer in more than two thirds of patients with a high sensitivity but lower specificity. In 80% of patients MRI detected lesions could be localized again by using ultrasound. Furthermore the size and localization of the lesions found on MRI most often correlated closely with findings at pathology. Breast MRI also provided the possibility of breast conserving surgery in one thirds of patients. CONCLUSION: Breast MRI can result in additional detection of otherwise occult lesions in occult breast cancer. Because of low specificity of malignant lesion detection by breast MRI, lesions should be histologically confirmed. This can be achieved either by MRI or ultrasound guided biopsy, as long as all MRI detected lesions are histologically checked. Routine application of breast MRI in occult breast cancer may also alter locoregional treatment by offering the possibility of breast conserving surgery in one thirds of patients.

Results of tailored treatment for breast cancer patients with internal mammary lymph node metastases.

Although the internal mammary (IM) lymph node status is a major prognostic factor in breast cancer, IM nodal staging is not common practice. In order to improve nodal staging, we have routinely performed IM sentinel node (SN) biopsy and have adjusted adjuvant treatment accordingly. We reviewed the outcome of these patients. Data from 764 patients were available for follow-up. A total of 406 patients had no lymph node metastases (group 1), 330 patients had axillary metastases (group 2), 7 patients had IM metastases only (group 3) and 21 patients had both axillary and IM metastases (group 4). Mean follow-up was 46 months. Prognosis did not appear to be worse for patients with IM metastases compared to those with axillary metastases only, which might indicate that they benefit from improved staging and tailored adjuvant treatment algorithms. However, long-term follow-up data, preferably in larger series, are needed to support our findings.

Additional tracer injection to improve the technical success rate of lymphoscintigraphy for sentinel node biopsy in breast cancer.

BACKGROUND: Sentinel node (SN) biopsy has become the standard of care in the treatment of breast cancer. The aim of this study is to determine the value of additional tracer injection to increase the technical success rate of the SN procedure and to identify factors that influence the ability to visualize hotspots. METHODS: From February 1997 to August 2007, 1,208 clinically node-negative breast cancer patients underwent lymphatic mapping for SN biopsy. The technique involved the injection of 370 MBq (10 mCi) Tc-99 m-nanocolloid peritumorally. In case of insufficient or absent visualization of hotspots 37 MBq (1 mCi) of additional tracer was given intracutaneously above the tumor. RESULTS: In 93 patients (7.7%) visualization of hotspots on initial lymphoscintigraphy was insufficient (41 patients) or absent (52 patients). The first 14 patients did not receive additional tracer injection. In five patients, additional tracer did not result in successful lymphoscintigraphy, which is correlated with massive nodal tumor infiltration. In 33 patients with negative initial lymphoscintigraphy, additional tracer injection resulted in secondary SN visualization. In 41 patients with faint hotspots on initial lymphoscintigraphy, additional tracer injection, by increasing nodal uptake, simplified accurate SN biopsy. Decreased radiotracer uptake in this group was associated with older age and high body mass index (BMI). CONCLUSIONS: Additional tracer injection following initial scan failure increases the success rate of lymphoscintigraphy during lymphatic mapping in breast cancer, without compromising accuracy. If additional tracer injection does not result in secondary SN visualization, gross nodal tumor involvement is often present and axillary lymph node dissection (ALND) is mandatory.

Internal mammary lymph drainage and sentinel node biopsy in breast cancer - A study on 1008 patients.

INTRODUCTION: Nowadays, axillary sentinel node (SN) biopsy is a standard procedure in the staging of breast cancer. Although the internal mammary (IM) lymph node status is a major independent prognostic factor in breast cancer patients, sampling of IM sentinel nodes (IMSNs) is not performed routinely. The aim of this study was to determine the likelihood of finding IM lymph node metastases in case of IM hotspots on lymphoscintigraphy and evaluate the relevance of IMSN biopsy as a method to improve staging. PATIENTS AND METHODS: Between April 1997 and May 2006, a total of 1008 consecutive patients with clinically node-negative operable primary breast cancer were enrolled in a prospective study on SN biopsy. Both axillary and IMSNs were sampled, based on lymphoscintigraphy, intraoperative gamma probe detection and blue dye mapping, using 10 mCi (370 MBq) (99m)Tc-nanocolloid injected peritumorally, and 0.5-1.0 ml Patent Blue V injected intradermally. RESULTS: Lymphoscintigraphy showed axillary sentinel nodes in 98% (989/1008) and IMSNs in 20% of the patients (196/1008). Sampling the IM basin, as based on the results of lymphoscintigraphy, was successful in 71% of the patients (139/196) and revealed metastases in 22% (31/139). In 29% of the patients with positive IMSNs (9/31) no axillary metastases were found. CONCLUSION: Evaluation of IMSNs improves nodal staging in breast cancer. Patients with IM hotspots on lymphoscintigraphy have a substantial risk (22%) of metastatic involvement of the IM chain. In addition, true IM node-negative patients can be spared the morbidity associated with adjuvant radiotherapy.

Incidence of axillary recurrence in 344 sentinel node negative breast cancer patients after intermediate follow-up. A prospective study into the accuracy of sentinel node biopsy in breast cancer patients.

Sentinel lymph node biopsy (SLNB) has been validated in the treatment of breast carcinoma and is considered to stage the axilla adequately in this disease. However, long-term follow-up data are scarce. We evaluated the results of SLNB with respect to loco-regional failures in the axilla in SN-negative patients with invasive breast carcinoma and analysed their causal factors. Between 1997 and May 2004, 656 patients without clinically palpable lymph nodes were included in our study. Data with regard to demographics, diagnostics, therapy and follow up were gathered prospectively from all patients. Patients treated after May 2004 were excluded from this study to permit at least one year of follow-up. Out of the 656 patients, 344 patients with a negative sentinel lymph node biopsy did not undergo axillary dissection and were followed up clinically. Median follow up was 43 months. In 3 patients (0.9%) axillary recurrences developed. All three patients subsequently underwent a completion axillary dissection, chemotherapy and radiotherapy. The low rate of clinical axillary recurrence after an intermediate follow up period suggests that a negative SN biopsy accurately reflects the nodal stage in patients with breast cancer.

Personality predicts quality of life six months after the diagnosis and treatment of breast disease.

BACKGROUND: Quality of Life (QoL) is an important outcome measure in oncology. QoL is influenced by personality traits, such as anxiety. To assess the influence of personality on QoL in women with breast cancer, a longitudinal prospective cohort study was done. METHODS: Ninety-one patients with breast cancer and 111 patients with benign diagnoses completed prior to the diagnosis and 1, 3, and 6 months after diagnosis and treatment a set of questionnaires. RESULTS: Overall QoL showed no significant differences between the two groups. The influence of trait anxiety was considerable for all measurement moments. Trait anxiety is accountable for up to 40.6% of the variance in QoL scores. Forty-five women in the benign group scored high on trait anxiety, and 40 women in the breast cancer group. Women with a high trait anxiety score were 3 times as likely to have a low general QoL six months after diagnosis and possible surgery, irrespective of the diagnosis (breast cancer or benign problems). When the women were divided into four groups based on the diagnosis and the score on trait anxiety, there was a significant difference in scores on general QoL between the groups on all measurement moments, with a significant lower score for the two groups with a high score on trait anxiety (P < 0.001). CONCLUSION: Trait anxiety rather than the diagnosis breast cancer determined whether patients experienced a low QoL.

Results of sentinel node biopsy not affected by previous excisional biopsy.

AIMS: Sentinel lymph node (SN) biopsy has been validated in the treatment of breast carcinoma. Patients with previous excisional biopsy are regarded as ineligible for SN biopsy. We evaluated the results of SN biopsy for this group of patients based on confirmatory axillary lymph node dissection. PATIENTS AND METHODS: From April 1997 all 88 patients with stage T(1-3) breast cancer who had previously undergone diagnostic excisional biopsy followed by complete axillary lymph node dissection, were enrolled into a prospective study to determine the validity of the sentinel node procedure. RESULTS: Lymphoscintigraphy visualized one or more axillary hot spots in 84/88 patients. A successful SN biopsy was performed in 87 patients. Complete axillary lymph-node dissection showed no false-negative SN biopsy among the 87 SN procedures. CONCLUSION: SN biopsy is a reliable and safe method following excisional biopsy as is confirmed by completion axillary lymph node dissection. Therefore, patients with previous excisional biopsy are eligible for sentinel node procedure and can be spared unnecessary axillary lymph node dissection.

Halsted revisited: internal mammary sentinel lymph node biopsy in breast cancer.

OBJECTIVE: To investigate the feasibility of internal mammary sentinel lymph node biopsy as a method to refine and thereby improve nodal staging in breast cancer. SUMMARY BACKGROUND DATA: The internal mammary lymph node status is a major prognostic factor in breast cancer. If positive, prognosis is less favorable. However, staging this regional nodal basin is not performed routinely, thus discarding additional staging information. METHODS: In a consecutive series of 256 patients with primary breast cancer, sentinel node biopsy was performed based on lymphoscintigraphy, intraoperative gamma probe detection, and blue dye mapping using 10 mCi (370 MBq) (99m)Tc-nanocolloid injected peritumorally and 0.5 to 1.0 mL Patent Blue V injected intradermally. During surgery, whenever possible, both axillary and internal mammary sentinel nodes were sampled. RESULTS: Lymphoscintigraphy showed axillary sentinel nodes in 95% (243/256) and additional internal mammary sentinel nodes in 25.3% (65/256). The overall success rate of axillary sentinel node biopsy was 97% (249/256). Sampling the internal mammary basin, based on the results of lymphoscintigraphy, was successful in 63% (41/65). In three patients a small pleural lesion resulted from staging this basin. This technique revealed internal mammary metastases in 26.8% (11/41). In 7.3% (3/41), internal mammary nodes showed metastatic involvement without accompanying axillary metastases. CONCLUSIONS: Internal mammary sentinel node biopsy is feasible without serious additional complications. It improves nodal staging in breast cancer by identifying higher-risk subgroups with internal mammary nodal metastases, which might benefit from altered adjuvant treatment regimens.

Sentinel node biopsy in 70 unselected patients with breast cancer: increased feasibility by using 10 mCi radiocolloid in combination with a blue dye tracer.

AIMS: Lymphatic mapping and sentinel node (SN) biopsy in breast cancer contribute to more accurate staging, while using less invasive techniques. The aim of this study is to improve the accuracy and feasibility of this concept, increasing the identification rate of the SN, by using an alternative technique. METHODS: In 70 unselected patients with primary breast cancer, of whom 51% had undergone previous excisional biopsy, lymphatic mapping was performed using 10 mCi (370 MBq) 99mTc-nanocolloid peritumorally, combined with an intradermal blue dye tracer. RESULTS: Lymphoscintigraphy showed one or more SN in 97% and harvest of the SN was possible in all patients (identification rate 100%). Axillary metastases were found in 39%. Sensitivity of the SN biopsy was high, both after primary surgery (93%) and after previous surgery (100%). Internal mammary lymph node biopsy following lymphatic mapping was attempted in all 24 patients (34%) with parasternal SN visible on the scan and was successful in 15 patients, revealing metastatic involvement in five patients. CONCLUSIONS: We conclude that SN biopsy, using a higher dose of peritumoral radiocolloid tracer, combined with intradermal blue dye tracer, increases feasibility in breast cancer, making this concept applicable for all patients with primary breast cancer.

Abscess of the spleen.

Two unusual cases are presented of splenic abscesses caused by metastatic infection with different organisms. The patients were treated with splenectomy and antibiotics.
