Minimally Invasive Treatments

The growing detection of papillary thyroid microcarcinomas (PTMCs) is paralleled by an increase in surgical procedures. Due to the frequent indolent nature, cost, and risk of surgery, active surveillance (AS) and ultrasound-guided minimally invasive treatments (MITs) are in suitable cases of incidental PTMC proposed as alternatives to thyroidectomy. Surgery and radioiodine are the established treatments for relapsing cervical differentiated thyroid carcinoma (DTC) metastases. But radioiodine refractoriness, risk of surgical complications, adverse influence on quality of life, or declining repeat surgery have led to AS and MIT being considered as alternatives for slow-growing DTC nodal metastases. Also, for distant radioiodine-refractory metastases not amenable to surgery, MIT is proposed as part of a multimodality therapeutic approach. The European Thyroid Association and the Cardiovascular and Interventional Radiological Society of Europe commissioned these guidelines for the appropriate use of MIT. Based on a systematic PubMed search, an evidence-based approach was applied, and both knowledge and practical experience of the panelists were incorporated to develop the manuscript and the specific recommendations. We recommend that when weighing between surgery, radioiodine, AS, or MIT for DTC, a multidisciplinary team including members with expertise in interventional radiology assess the demographic, clinical, histological, and imaging characteristics for appropriate selection of patients eligible for MIT. Consider TA in low-risk PTMC patients who are at surgical risk, have short life expectancy, relevant comorbidities, or are unwilling to undergo surgery or AS. As laser ablation, radiofrequency ablation, and microwave ablation are similarly safe and effective thermal ablation (TA) techniques, the choice should be based on the specific competences and resources of the centers. Use of ethanol ablation and high-intensity focused ultrasound is not recommended for PTMC treatment. Consider MIT as an alternative to surgical neck dissection in patients with radioiodine refractory cervical recurrences who are at surgical risk or decline further surgery. Factors that favor MIT are previous neck dissection, presence of surgical complications, small size metastases, and <4 involved latero-cervical lymph nodes. Consider TA among treatment options in patients with unresectable oligometastatic or oligoprogressive distant metastases to achieve local tumor control or pain palliation. Consider TA, in combination with bone consolidation and external beam radiation therapy, as a treatment option for painful bone metastases not amenable to other established treatments.

Abstract Introduction: Bone metastases from differentiated thyroid cancer are generally resistant to radioactive iodine (RAI) therapy and are associated with poor prognosis, except for RAI-avid bone metastases with no structural correlate on imaging studies. Case: A 59 y/o woman presented for the evaluation of non-toxic multinodular goiter. Thyroid US showed a 2.7 cm nodule meeting FNAB criteria and no suspicious cervical lymph nodes. Cytology reported a Bethesda IV category with ThyroSeq V3 positive for chromosomal copy number alterations and a high Na+/I− symporter (NIS) expression (27%) with an ~ 60% probability of cancer. The patient underwent left lobectomy with isthmusectomy without neck dissection. Surgical pathology showed a 3.5 cm papillary thyroid carcinoma with extensive angioinvasion (≥4 vessels), negative margins, no ETE, and did not contain a BRAF V600E mutation. Completion thyroidectomy, in anticipation of RAI treatment, showed no additional tumor. Post-operative Tg after 6 weeks was unexpectedly high at 69 ng/mL (negative Tg Ab, TSH 5.7 uIU/ml) which prompted a rhTSH I-123 RAI WBS with SPECT/ CT and a diagnostic chest CT to uncover possible distant metastases. There was RAI uptake in the thyroid bed and right anterolateral 9thrib without a CT correlate (no osteolytic lesion) but with a signal abnormality on MRI. She was categorized as T2NxM1, 8th Edition AJCC Stage IVB, and ATA high risk. She was treated with 148.3 mCi I-131. Unfortunately, 6 months later the Tg was elevated and rising (Tg 38.4 ng/mL, negative Tg Ab, TSH 0.05 uIU/ml). A second diagnostic I-123 WBS with SPECT/ CT showed a new recurrence in the neck but no uptake in the rib lesion on planar images or other distant sites. Because of the unusually high Tg without any RAI-avid metastatic disease, an 18-FDG PET/CT was ordered to search for non-RAI avid disease. This showed disease confined to the neck and increased sclerosis of the rib lesion without increased FDG-uptake consistent with treated disease status post-RAI. There were no other distant hypermetabolic lesions. The left thyroid bed lesion was biopsied and consistent with Bethesda VI cytology and she will soon undergo left central neck dissection with tumor resection. Discussion: RAI-avid bone metastases without structural correlate on high-resolution imaging are a subtype of bone metastases located in the marrow. They do not present as the typical lytic lesions from cortical destruction. They often resolve following RAI treatment, do not cause skeletal-related complications, and do not significantly affect prognosis. The combination of high NIS expression and increased vascularity in the bone marrow (as opposed to the protected microenvironment in the bone cortex) makes them vulnerable to RAI treatment. Recognition of this subset of bone lesions may prevent overtreatment with high doses of RAI treatment and avoid the use of bisphosphonates or external beam radiation.

Salvage Hifu

99 Background: One third of patients treated with External beam radiation therapy (EBRT) for localized prostate cancer (PCa) experience local recurrence. Salvage treatment options include prostatectomy, cryoablation, and High Intensity Focused Ultrasound (HIFU). Whole gland treatment in these patients offers acceptable cancer control, but carries a risk of severe urinary incontinence in at least 20% of cases and reduction of Quality of Life (QoL). In patients with unilateral local relapse, focal HIFU is feasible. The aim of this prospective study was to evaluate the effect of Hemi HIFU in patients with unilateral recurrence after radiotherapy. Methods: Between 2009 and 2012, 48 patients were prospectively included in 2 centers. Inclusion criteria were positive MRI and biopsy in one lobe diagnosing unilateral cancer after EBRT (46 patients) and after brachytherapy (2 patients). Mean age was 68.8 ± 6 years, mean pre HIFU PSA was 5.2 ± 5.2 ng/mL and the repartition of Gleason score was ≤7: 28, ≥8: 18 and not determined: 2. Median follow-up was 16.3 months [range 3-43]. Treatments were performed with Ablatherm® HIFU device. Results: The mean PSA nadir value was 0.69 ± 0.83 (median: 0.4). Disease progression occured in 16 patients (35,5%). Local recurrence was found in 4 patients in the controlateral lobe, and in 4 patients in both lobes. Six patients developped metastases and 2 had rising PSA without local recurence or proven metastasis. Fifteen of these 16 patients received salvage treatments (3 re-HIFU, 11 androgen-deprivation, and 1 re-HIFU plus androgen-deprivation). Thirthy-six patients (75%) were pad-free. Seven patients (14.6 %) required 1 pad a day. Severe incontinence occured in 5 patients (10.4%). One of them received artificial urinary sphincter. Paired results indicated no significant change in QoL and IPSS scores: EORTC-QLC-30: (from 35.7 ± 8.7 to 36.8 ± 8.6, p=0.22) and IPSS: (from 7 ± 5.6 to 8.5 ± 5.1, p=0.13) Conclusions: Hemi-salvage HIFU is efficient in patients with unilateral radio-recurrent PCa with a preserved QoL offering comparable cancer control to whole gland treatment.

Free Survival

109 Background: In the absence of randomised study data institutional series have shown High Intensity Focused Ultrasound (HIFU) to produce excellent overall and cancer specific survival rates in patients with localized prostate cancer (LPCa) compared with alternative curative treatments. The aim of this study was to evaluate the oncologic outcome of patients treated with HIFU versus conformal external beam radiation therapy (C-EBRT) without previous or associated androgen deprivation(AD).This study was designed to overcome limitations of case series studies by using a matched pair design in patients treated contemporaneously with HIFU and C- EBRT in two institutions in the same town. Methods: 256 eligible patients with intermediate risk prostate cancer (d’Amico classification) treated between 2000 and 2005 were prospectively followed and matched to a 1:1 basis following know prognostic variables: prostate-specific antigen (PSA) level and Gleason score.190 perfect matches of patients (95 in each group) were further analysed. Progression free survival rate were the primary endpoint. Other endpoints were secondary used of salvage therapy, and survival rate without salvage palliative androgen deprivation therapy (S-ADT).The progression free survival rates were calculated with Kaplan-Meier estimate. For progression free calculation, failure was defined using the Phoenix definition (nadir + 2ng/ml) or at the time of a salvage treatment for local relapse evidenced by control biopsy. Results: The seven years progression free survival rate was not significantly different after HIFU than after C-EBRT (47% versus 52%, p: 0.311) . The palliative androgen deprivation free rate at seven years was significantly different after HIFU than after C-EBRT (85% versus 58%, p: 0.002). Conclusions: The progression free survival rate was not significantly different after HIFU use than after C-EBRT but the rate of patients who need palliative S-ADT was significantly different after HIFU or C-EBRT: Higher rate of S-ADT was associated with C-EBRT use than with HIFU use.

Background: Several reports suggest testosterone replacement therapy (TRT) may be an option in selected hypogonadal patients with a history of prostate cancer (PCa) and no evidence of disease after curative treatment. Our aim was to assess TRT experience and patient management among urologists in Bavaria. Materials and Methods: Questionnaires were developed and mailed to all registered urologists in Bavaria (n = 420) regarding their experience with TRT in patients with treated PCa. Results: One hundred and ninety-three (46%) urologists returned the questionnaire and reported their experience with TRT in hypogonadal patients after curative treatment for PCa. Complete data was available for 32 men. Twenty-six patients (81%) received TRT after prostatectomy, 1 patient after external beam radiation, 3 patients after high-dose brachytherapy and 2 patients after high-intensity focused ultrasound. Of the PCa cases, 88.5% (23/26) were organ confined (pT2a-c), and 3 were pT3 tumors. All patients were pN0/cN0, and only 1 patient (pT3a) had a positive surgical margin status postoperatively. After a mean follow-up of 39.8 months, no biochemical relapse was observed. Conclusion: To date, there is no clear evidence to withhold TRT from hypogonadal men after curative PCa treatment. Our findings, although with limitations, fit in with the available data showing that TRT does not put patients at an increased risk after curative treatment of PCa.
