Inclusion Criteria:

* 1\. Following lesion criteria applicable for biopsy:

  1. Lesion safely accessible (no visceral or vessel interposition; in the case of a transvaginal approach no vaginal stenosis (severe atrophy - virgo - vaginismus); within reach of biopsy needle)
  2. Solid component present (purely cystic lesions excluded)

     2\. Biopsy for research purposes, the following is applicable: Patients with a gynecological tumor eligible for participation in academic or commercial clinical trials requesting a biopsy for translational research. For the current study, which is observational, we do not intend to take additional biopsies outside routine clinical practice, but only biopsies requested for participation in other (interventional) studies on systemic treatment in gynecologic oncology.

     3\. In case of a diagnostic biopsy, one of the following inclusion criteria should be applicable:

  <!-- -->

  1. Suspicious primary disseminated gynecologic tumor (tumor itself or metastasis) Patients with a presumable new diagnosis of a disseminated pelvic tumor where histological confirmation of disease is necessary before the possibility to start a specific oncologic treatment and

     * Are invalid candidates for primary (radical) surgery due to comorbidities or poor overall general wellbeing
     * Are invalid candidates for primary (radical) surgery due to the extensive disease-spread according to imaging and/or diagnostic laparoscopy
  2. Suspicious primary disseminated NON-gynecologic tumor (tumor itself or metastasis)
  3. Patients with possible recurrence of a gynecological tumor (cervix, myometrial, endometrial, ovarian etc), where histological confirmation of disease recurrence is necessary before the possibility to start a surgical or systemic intervention.
  4. Patients with possible recurrence of a presumably non-gynecological tumor, where histological confirmation of disease recurrence is necessary before start of treatment.
  5. Solitary tumor of unknown histology localized in vaginal wall, parametria, retroperitoneum or uterine wall and can be punctured without spilling in abdominal cavity.

Exclusion Criteria:

\- 1. Patients \< 18 years 2. Clotting defect or anticoagulation therapy, precluding a safe biopsy even with adapted therapy regimen.

3\. Vaginal or pelvic infection 4. Poor performance status contraindicating any specific oncologic treatment

Outcome Measures

Primary Outcomes

Safety

Defined as absence of procedure-related complications. Procedure related complications will be graded by Clavien-Dindo classification.

Time frame: 6 weeks

Tissue yield

Defined as sufficient amount of tissue for histological analysis. This will be a binary variable based on the pathology report.

Time frame: 6 weeks after procedure

Secondary Outcomes

Factor 1 affecting safety and tissue yield

A number of biopsies per target lesion,

Time frame: 6 weeks

Factor 2 affecting safety and tissue yield

The length of the needle shot (15 vs 22 mm).

Time frame: 6 weeks

Factor 3 affecting safety and tissue yield

The thickness of needle (16-18 Gauge).

Time frame: 6 weeks

Factor 4 affecting safety and tissue yield

The target lesion histotype - categorical variable defined by the tumour type.

Time frame: 6 weeks

Factor 5 affecting safety and tissue yield

The target lesion size in mm.

Time frame: 6 weeks

Patient experience

Assessment of patients' overall experience using VAS-Score.

Time frame: 3 days

Patient pain score

Assessment of patients' pain and discomfort during the procedure using VAS-Score.

Time frame: 3 days

Histological diagnosis

Comparison of biopsy result with final histological diagnosis: histological type (only in patients finally undergoing surgery). Binary variable indicating agreement.

Time frame: 6 weeks
